GTX1060. no sound via HDMI

spirt · December 29, 2016 at 11:18 AM

Just made an upgrade of my old GTX770 to GTX1060 and got problem. No sound via HDMI output on my TV. At the same time under Win10 everything works perfect.
I tried various models of GTX1060 and HDMI cables. v7.90.008/009/010 and builds from this tread LibreELEC (generic and nvidia) didn't solve this issue also.

Thank you in advance for any thoughts.

Check the sound output device in de system sound settings? It can point to the wrong device.

I managed to get NO sound at all after a nvidia driver update and had to remove all nvidia hdmi devices and restart windows to auto detect it again. But that is perhaps not the same as your case.

Post a kodi debug log.

Post the output of:

Code

grep audiodevice ~/.kodi/userdata/guisettings.xml

and:

Code

aplay -L

can't hurt either.

Do you perhaps have it muted?

spirt · December 30, 2016 at 6:16 AM

of course not. both TV and LE client are not muted.

I know it sounds dumb but I had another user with "no sound" and they just had it muted. So I just wanted to rule that out.

Does HDMI audio work with any other Linux distribution?

Are you using any adapters? DP to hdmi or mini hdmi to hdmi?

No extra adapters. Just direct connection by HDMI cable from videocard to TV.
Din't have time for other Linux distibutions. Plan to try it during Xmax holidays.
Just want to remind that under Win eveything works purfect.
And in my debug log you can see many errors 'ERROR: ffmpeg[7F68DFFFF700]: [h264]'. Think they linked with my problem.

And i found one more suspicious moment:

That's just a red herring, nothing is wrong there.

Tried Ubuntu 16.10
The problem is still there - no sound.

spirt · January 19, 2017 at 5:38 PM

New LibreELEC (Krypton) v7.95.1 and again no sound

vitorp07 · January 19, 2017 at 8:31 PM

This happened to me a while ago, something to do with the TV,GPU(audio) and HDMI config.

Try to get sound by switching to these settings in system settings/Audio, set "Output configuration" to "fixed" and "Limit sampling rate" try all of them(starting from 44.1) to see if you get sound.
