Sound stopped working with kernel26-2.6.22.1-4

Before I updated to kernel26-2.6.22.1-4, everything was working fine. Digital output, ac3/dts with 5.1 surround and stereo output. Now, interestingly digital ac3/dts through spdif works, stereo does not. I have followed the ALSA guide and all modules and everything seems to be loaded and working. What else, everything is unmuted in alsamixer, including IEC958 and IEC958 P on 0% volume.

Please help! What am I missing? Digital output is working but I can't play analog output (mp3, etc.).

The highest sounds are the hardest to hear. Going forward is a way to retreat. Greater talent shows itself late in life.

Does your sound card have any other outputs besides front stereo? Maybe it's swapped front/rear or defaulted to headphone... Also, check your amp / cables for analogue.

Sorry, my description was confusing. My speakers are connected using optical out (spdif), and as I said, digital passthrough is working but I cannot play regular analog formats. I guess we can rule out ALSA then? Maybe it's some faulty mp3 decoder...

Re: Sound stopped working with kernel26-2.6.22.1-4

I had exact the same problem after a pacman -Syu
The only way I was able to fix it by downgrading to kernel26-2.6.21-?
