readeon hdmi audio (snd-intel-hda) on current

chemfire · 09-18-2013, 06:10 AM

Hi guys;

I upgraded a box to current the other day. I can't seem to get any sound over hdmi on a radeon HD5540. It was working fine before.

Yes have the correct default pcm device set in alsa, and I can see the device reported in aplay -l; alsa mixer etc. It all looks correct. Software "plays" sound you just can't hear anything.

I have see some reports around the net this is a kernel regression. Can anyone here confirm?

If youŕe using alsa, I would grok /etc/asound.state. I had fierce issues because capture was turned off. Every bootup, it ran ´alsactl restore´ and turned it off again¬!

I don't think its a mixer issue. If I play longer audio file, like a mp3 with mpg123 just to test. I finished almost immediately with no errors. Its like as fast as the CPU can get through decoding the file.

I'd settle for a decent error message some place so I'd have some idea of what's wrong.

This is the lay of land as seen in /proc or Alsamixer

If we're still here, check /etc/asound.state. Everything else can be perfect, but if you set a switch to off . . . .There may also be some funny module for hdmi audio - I dunno.

business_kid,

Thanks for the replies. I tried getting rid of the file and rebooting, nothing would have been attempted set on controls.

I also got rid of /var/lib/alsa/asound.state (which I think is the one in active use, as it gets rewritten when when I run alsactl store )

No determinable effects though.

Is this odd?
cat /proc/asound/devices
2: [ 0- 3]: digital audio playback
3: [ 0- 0]: hardware dependent
4: [ 0] : control
33: : timer

Should there be a device number for timer?

/var/lib? Looking here, my /etc/asound.state is a symlink to /var/lib/alsa. My bad. No, apparently the times should not have a number. Here's my sound card
