    The thing that is puzzling me is that, when it happens and I switch the TV off, why does it go to PSOD and why does it stop responding to the remote? And why, if I don't switch the TV off and I try and change channel did it lose the aerial signal?

    It makes me think of the situation where you leave something touching the keyboard of  PC and you fill the input buffer and then you get a stack overflow which screws up the whole thing.  This used to happen with early PCs and the "New Improved" ones these days seem to be able to cope

    My working hypothesis remains that you and Nick have boxes with faulty hardware.

    Do you have any evidence to contradict this, like having got a replacement box, and the issue remains the same?

    Also, it takes two to tango, so should we perhaps let suspicion fall on your TV? What make and model is it?

    And have you tried a different HDMI cable?

    And there are - or were - four places where sound could emerge from a YouView box - HDMI, SCART, Digital Out, RCA (Phono) plugs.

    Are these all affected when the issue occurs, or just some, or even just the one?

    Not that I am suggesting you should change where you get your sound from, of course.

    And apologies if I am going over old, perhaps well-worn, ground, but a resummarisation may be helpful here.

    Roy, I am starting to think that you are right and it is hardware.

    Nick's original thought, that it was related to YouView channel/software changes seems to have been disproved as it has happened to him and not to me on the same day, with the same software versions.

    I have not tried any of the changes you suggest as, since as the problem is a) intermittent and b)infrequent, I am reluctant to change anything until the problem can be consistently reproduced/predicted. The simple (and selfish) fix for me would be to walk into John Lewis and tell them that the box is faulty and that I want a replacement

    The TV is an LG32LD490 (bought 2011). Connection to the T2000 is HDMI. There is no sound bar etc. or other gubbins between the Humax and the TV.  There is a Now TV box and a Chromecast into the TV (both via HDMI). The Humax is cable-connected to the router

    I think the next step for me is to revert to my (faulty - HDMI port failure) T1010 box to record programs and watch the existing recordings from the T2000 and, when they are finished, return the box as faulty (warranty is good until March 2019 (JL 2 year guarantee)

    I've often wondered if this intermittent problem was a third party kit compatibility issue (as I've concluded with mine). Because with me it happens nearly every time I change a channel.
    I often change my boxes around (T2000 & a T2100) and neither display this behavior when directly connected to a Samsung TV, but always do it when connected to my Yamaha sound system and Sony TV.
    One interesting thing to note is trophytr5's problem of sound loss and PSOD, as I've never seen anyone report that before. Its usually one or the other.

    Has anyone else tried switching the TV off and back on after the loss of sound though?  "Most" people, faced with a problem like this would just do a restart each time and not have the curiousity to follow it up.  Unfortunately, for me, that's not the way I work.

    I've tried turning the TV off/on on a few occasions when this has happened. The sound doesn't return and the picture continues playing.

    Here's my latest report which was posted in another place...

    This happened again today (12/09/17)

    Again lost sound when changing channel from 231 BBC News to 101 BBC One HD.

    This time I changed channel via the guide. After selecting 101 BBC One HD, the guide flickered for 3-4 seconds before then showing the channel without any sound.

    Tried a few things to recover sound:

    - Removed and reinserted HDMI cable.

    - Switched to other channels which reportedly have different encoding.

    - Played content from iPlayer

    - Toggled all the audio settings for the box. Including Audio Feedback which didn't provide any audio feedback!

    - Turned TV on and off.

    - Put YouView box into standby for 10 minutes.

    None of these worked and had to soft reset the box to restore sound.

    On 12 Sept, it didn't happen for me. So that, to me, points away from channel/software changes.

    I'm thinking of just going out and buying a new Humax, running down recording on the "old" T2000, while making all new recordings on the new box.  Then throwing the "old" T2000 back at JL as "broken". 

    I've remembered the other problem with the T1010.  As well as a failed HDMI port, it is also reporting a significantly lower signal strength than the T2000 on the same aerial socket.  Tomorrow, I'll check the recordings from tonight to see if they are poor quality

    I have also considered a new TV but it's a big layout when I have a perfectly good one (I believe). and no need for a second TV

    Thursday 21 Sept - It did it again.

    No sound on changing from CH1 to CH107. The usual flicker from the channel indicator (bottom left) before new channel starts with no sound
    A new channel (Forces TV CH96) introduced today.
    Tried iPlayer - no sound
    Tried Netflix - It said it was having trouble playing the sekected program after getting to 4% loaded.
    Switched TV off and back on again. No PSOD. Still no soound.  Changed back to CH1. No sound, but no re-occurence of the loss of signal.

    Switched TV to T1010 on SCART socket.  All good. Sound on all channnels and on iPlayer and no problem playing from Netflix.

    Switched TV to NOW TV on HDMI. All good

    Switched back to T2000 on HDMI. Still no sound. Still not playing from Netflix
    Tried most of the things on Watne's list. None had an effect

    Warm restart (and should there be little click after the 8 second hold?)
    All good after restart. Sound back. Netflix working. The bad news is that I forgot to reset the channel CH1 before the warm restart, so I wasn't able to reproduce Suday 17th test/result

    Not sure if this is the same fault but I have something that sounds very similar.

    We get no sound from any of the Freeview HD channels unless we sit there in silence for about 30 seconds and then the sound comes out and everything works OK.   But if I do anything at all - even something as innocuous as pressing the youview remote control mute button on and off or changing to another HD channel - and the sound goes away again until some time passes and then it comes back.  SD channels work fine.

    I've changed nothing in our set-up.. this just started happening.

    Setup:

    HUMAX DTRT1000 / 80B07000
    Component Software 3.2.92 (abd44b)
    Manufacturer Software 28.35.0
    Platform / ISP configuration 3844 / 253
    This is a retail Freeview/Youview box that has been hijacked by BT's software/branding since switching to BT Infinity a year or so ago.

    HDMI output to Octava HD41ARC to Sonos Playbar (optical)

    Nothing has changed in the setup over the period when the fault appeared apart from whatever software updates will have been pushed to the freeview box (or Sonos)

    I could swear I'd already tried this but I just rebooted the Humax box again - as in full power off, wait some time, power back on.  And it seems OK again now.  So sounds like my problem was indeed different to those being described by others on this thread.  Thanks for the suggestions.

    Doing that is a slightly agricultural, slightly brutal, and slightly incomplete version of the proper soft reset.

    If it has benefited you, I suggest you do the proper soft reset at the earliest opportunity to ensure you get the full benefits from it.

    ha! I did have _another_ reason for turning the power off without any particular elegance...  but good point... I'll try to soft reset at the weekend.  Thanks.

    A thought.

    If I plug the T2000 into the TV by BOTH the Scart and HDMI sockets will I be able to switch the TV input from one to the other?

    If I can, then, the next time the sound goes off when connected via HDMI, if I switch to SCART and the sound comes back, would that tell us anything worthwhile?

    I ask as it will be a pain to do. The T1010 can only be plugged into the TV's only SCART socket since the HDMI port on the T1010 broke. As I am using the T1010 for all new recordings, in case I need to return the T2000, it would mean re-plugging the SCART lead every morning to set up the days recordings.

    Yes, SCART and HDMI are simultaneous.

    Yes, if the SCART sound stays live, I think that tells us this is an HDMI handshake issue of some sort, as we know that while HDCP is always on with the YouView box, it gets active when you switch to an HD Channel.

    There are all sorts of solutions to the SCART plugging issue.

    One is to do your daily scheduling from the YouView App - if you download both the retail YouView and the BT YouView app, you can pair one with each box.

    Another is to use a SCART switcher box, if you have one handy, so you can just switch as required, not have to replug.

    Another is not to plug the SCART from the T2000 into the TV at all, but to take the sound off to somewhere else, as you don’t need the picture; use a SCART to phono adaptor to get the sound on a mini hifi, or even a pair of headphones?

    Though check that works, and you can hear it OK, before encountering the next whoopsie, so you know you are ready for it.

    Thanks, Roy.

    It's a cunning idea to use two different apps to program the 2 boxes.  Instead of using the retail and the BT versions, I'll try putting the app linked to the T1010 on my phone and the one linked to the T2000 on my tablet.  I think that will work.

    EDIT It does.

    I had a SCART switch box, but I can't find it now.  It probably got recycled as "old" technology.  The pace of change!!!  I have a box of "old" PC leads if anyone wants them.

    I just so happen to have a SCART to phono adapter, but why can't I just use the phono out sockets on the T2000?  I already have that set up, but I don't usually have the hifi powered up. But I've checked and it does work

    You can use the phonos. See my posting above, from four days ago, when I suggested it :-)

    Saturday 23rd September

    Switched T2000 on, switched TV on, switched hifi on with input as the phono output from the T2000.  All working. Nasty echo with hifi on and TV sound not muted
    Waited from a short time (couple of minutes)
    Changed from CH1 to CH107 - no sound on TV. No sound on hifi
    Changed from Ch107 to CH1 - no sound.
    Switched TV off, waited till the blue power light turned red, switched TV on - no sound (but no PSOD!!)
    Switched T2000 off with remote. Went for a dump.  Switched T2000 back on - no sound
    Switched T2000 off on front panel and back on - no sound
    Did a warm restart of T2000 from front panel - sound is back on CH1
    Changed CH1 to CH107 - no loss of sound. TV and hifi both producing sound.

    It may be that because I did something different, i.e. switched channels almost starightaway instead of watching CH1 for up to 30 minutes, this provoked the loss of sound.

    I'll try a quick switch again tomorrow (Sunday)

    I called into John Lewis yesterday to update them on the situation and they told me that my best course of action is to call Humax (under their one year warranty) fora replacement box.  If they take it in, they will have to test it before getting humax involved.  Quicker and easier for me to contact Humax directly, although I am not looking forward to dealing with Customer Services

    This happening on all sound outputs would seem to put all HDMI handshake problem theories to bed. Which is progress, of a sort.

    There is, by design, a mute when you change channels, or you would get some nasty switching noises.

    And I have heard those on my T1000 in the early days.

    But it seems like your box does not unmute again after the channel change, as it should..

    And this seems to be. a hardware issue with your box, as it survives all resets..

    Possibly a Humax firmware issue, though I don’t think you and Nick quite make a quorum for that.

    I keep, in the back of my mind, that this might somehow be related to your very rare, but very real, and acknowledged as such, tuning issues.

    And IIRC, YouView fixed these, only to find worse problems in the fixed version, which was hastily withdrawn; and despite promises, a fix never did come out.

    Do they still happen on NextGen? If so, and they are related, a new box is going to do the same :-(

    But I do hope not; and either way, we, and YouView, learn something.

    The guy is JL also thought it was an "unmute failure" when I first went in.  And I am increasingly thinking it IS hardware or firmware related

    I am still clearing the backlog of recordings on the T2000 ready to call Humax for a warranty claim.

    How do I find out what version of the firmware I am currently on?  I can't find out which version the box(es) are running. All I see is the legend in the bottom left of the screen on a warm restart which says UKTFAA 0.05.

    When I was in JL on Friday, another of their staff printed out a page from the Humax Support site which showed the latest software version and how to load it from a USB stick.  But I didn't twig until this morning that it was the HDR-2000T (Freeview) and not the DTR-T2000 (YouView).

    The Humax site doesn't list software downloads at all for any of the YouView boxes

    I had to search back to find that other thread as I couldn't remember the problem!!
    https://community.youview.com/youview/topics/wont-record-bbc1hd
    That problem hasn't re-occured since I thought it was fixed (before Sanj said it was).

    Settings/Software Information - Manufacturer software is the YouView version, and Component software the firmware, though they aren’t updated separately.

    If there is an update for you, pressing that Update Software Button will fetch it from YouView for you, but it is unlikely, as the box checks every day in the wee small hours anyway, and updates automatically if it finds a newer release than the one it has.

    Glad the other issue got fixed, anyway.

    Summary for September.

    Totals days tested - 26 (away for 4)
    Total days when problem occured - 6
    Longest period without encountering the problem - 7 days
    Shortest period between encountering the problem - 2 days
    On 2 days, turning the TV off after loss of sound gave a PSOD. 
    On 5 days, doing a warm restart seems to have fixed the problem.
    On 1 day (17th), a warm restart appeared to have fixed the problem, but it re-occured when switching from CH1 to CH107. Note that this was the only day when I switched the T2000 from CH107 back to CH1 before the restart.
    Days with no test - 4, 5, 6, 7
    Days with no failure - 2, 3, 8, 10,11, 12, 13, 14, 16, 18, 19, 20, 22, 24-30
    Days with failure - 1, 9, 15, 17, 21, 23

    Only on one occasion (23rd) did I test to see if there was any sound at all (RCA to HiFi) and there wasn't.

    I still have 3 hours of TV unwatched on the T2000 before I am get in contact with Humax to (Possibly) replace the box

    Switched TV off and back on again. No PSOD. Still no soound.  Changed back to CH1. No sound, but no re-occurence of the loss of signal.

    Switched TV to T1010 on SCART socket.  All good. Sound on all channnels and on iPlayer and no problem playing from Netflix.

    Switched TV to NOW TV on HDMI. All good

    Switched back to T2000 on HDMI. Still no sound. Still not playing from Netflix
    Tried most of the things on Watne's list. None had an effect

    Warm restart (and should there be little click after the 8 second hold?)
    All good after restart. Sound back. Netflix working. The bad news is that I forgot to reset the channel CH1 before the warm restart, so I wasn't able to reproduce Suday 17th test/result

    I get this occasionally, but going the other way, HD (101) to SD (1). But it is not limited to NextGen nor my current T2000, I also recall it occasionally on my now defunct T1000. It doesn't occur often enough to be more than a minor annoyance

    I have sent a email to Humax and received the standard response - Maintenance Mode Software Reset (done) and then Maintenance Mode, Delete Recordings (not yet done, next couple of days probably)

    It's been 12 days since it last happened. The only change is that I now use a Logitech Harmony remote (the LG remote has just about given up the ghost!). The only change that brings is that it turns the TV on first and then the T2000, rather than the other way round which I would normally do.  Once I realised this, I reverted to the LG remote for the first switch on of the day

    I wouldn't bother with Maintenance Modes etc at this point as I've been told Humax have been actively investigating this issue for a little while now. I'd wait and see if a fix gets put in place first.

    Hi everyone,

    Just to let you all know that this is still something which is on our radar and the team are looking into it at the moment. 

    I'll pop back in when I have any updates or need further information at all.

    Thanks for your patience!

    Did the Maintenance Mode Reset, Delete Recordings on Sunday, 8th
    I have been hiding 1 more channel each day since the reset, just in case the problem is connected to channel changes. I forgot to set the box to CH1 on Sunday night, so there was no test yesterday, but I lost sound this morning. This was followed, after the TV was switched off and on, by the PSOD.

    I have contacted Humax again and received the warranty form.

    Sarah, should I return the unit or wait for "the team" to reach a conclusion?  I still have 5 months of the Humax warranty to run (and the "old" T1010, so I can wait a while and carry out further tests, if it helps to pin down the problem

    It's being exchanged on Monday 16th October. 
    I'll carry out the same tests on the replacement box

    The old box had a real wobble on Sunday (must have known it was going back!!). Instead of the usual 6 second flicker, it went on for about a minute before completing the channel change with no sound.

    I received the replacement box on Monday and it was fine on Tuesday morning.  I hid the QVC channels (does anyone watch this c**p), watched a bit of TV from the T2000, caught up with some recorded programs from the T1010, and left the T2000 set to CH1 when I went to bed.

    Got up this morning, switched on T2000, switched on TV, waited for the YV menu to disappear, then switched to CH107.  Flicker, flicker, NO SOUND.  Switched TV off and back on.  PSOD. Did a warm restart and it was OK

    So it doesn't look like a hardware problem unless both boxes have the same obscure fault.

    It might be connected to the combination of the T2000 and the LG TV, but if this is the case, what is happening to cause the T2000 to lose sound on both HDMI and RCA and need tobe restarted to fix the problem, and why does it not then re-occur?

    So my suspicion is that it is a software fault, possibly triggered by a change in the channel list

    OK, if a second box does it too, I think you are correct.

    I suspect that like the problem you had originally, this is a corner case provoked by the particular combination of transmitters and channels in your particular location.

    I also suspect, on no evidence beyond a gut feeling, that a Huawei box, even on the ‘same’ YouView code wouldn’t do this, and that this is a Humax firmware issue.

    I wonder if YouView would offer to loan you a Huawei box, and prove me right or wrong?

    Interestingly, this morning I didn't lose sound AND the number of channels increased to 157. I think this was FreeSport being added. EDIT However, it did take a while to make the channel change.  ENDEDIT

    So it might not be connected to the channel list changing

    EDIT Humax are suggesting that a further replacement box might solve the problem. I think the odds of that are pretty low
    ENDEDIT
