[AUDIO] pch a110 no sound via hdmi

[dilyan]

hi, I got a strange problem with my pch a-110.
I usually use it with Panasonic 37'' plasma, with HDMI cable, settings:
Audio/Video:
- Video otput: HDMI -> 720p 50 Hz
- Frame rate sync: off
- Video Zoom: Fit to screen
- TV type: 16:9
- Colorspace: 16-235
- HMDI audio: on
- Surround mode: stereo
- DTS: analogue (PCM)
- Dolby Digital: analogue (PCM)
- AAC: analogue (PCM)
- WMA Pro: analogue (PCM)

I moved it to an older TV with composite cable (key combination TV mode + 0 made it work).

The interesting thing happened when I switch back to the Pana TV - no sound thru HMDI; sound is present only thru composite!

What I have tried:
- reset from the front "reset button" - not working
- downgrade to previous FW - not working
- again upgrade to the latest FW - not working
- all possible combinations with the Audio/Video settings (Auto Video Output, 1080i, 576, 720p 50/60 Hz), HDMI audio on/off - not working
- reset to factory defaults from the Maintenance menu - not working;
- changed the HDMI cable - not working;
- changed the TV to 32'' Sony LCD - not working;

The ONLY format working is DVD - have sound thru the HDMI; nothing else: mkv, avi (with MPEG1, with Dolby Dogital) works!

any suggestions and help is welcome.

Thanks!

there's also no sound from flac and mp3 formats.

I am experienced linux user, if logs are needed - just tell me which.
If somebody knows where the pch is keeping the settings, or its player mono - give me a hint!


dmesg, ps aux, top commands are not showing anything unusual.

OK, with top command i saw how the system is playing an mp3. Starting it from command line I get:
-----

It may be related, it may not.

I found that all MPEG1 audio encoded movies did not play via HDMI to my Samsung 32" TV.
If I turned up the sound I would get crackling noises
Rebooting the popcorn A110 (latest firmware at time of this post), did not resolve the problem

I turned the A110 OFF, using the hard switch and the TV, not just stand-by
Once powered back up, all was good

I also have issue with MPEG-1 and MP3 format on some files playing via HDMI.

An example of one such file is:

Normally most issues with audio can be rectified by setting DTS to RAW mode. However, after trying all settings for audio, I didnt manage to resolve the issue. Im starting to think that its the way its been encoded, as opposed to the PCH, but would like 2nd opinion of someone knowledgeable.

Settings are:

Audio/Video:
- Video otput: HDMI -> 720p 50 Hz
- Frame rate sync: off
- Video Zoom: Fit to screen
- TV type: 16:9
- Colorspace: 16-235
- HMDI audio: on
- Surround mode: stereo
- DTS: RAW
- Dolby Digital: PCM
- AAC: PCM
- WMA Pro: PCM


Thanks in advance...
