Details

After updating to the latest 2.6.21 kernel, the sound in KDE applications stopped to work. Oddly, while playing files with vlc, the sound works sometimes, but sometimes it hangs until vlc quits.

I have the same problem - some programs (cmus, mplayer) play sound OK, some just repeat 1/2 second endlessly (mpd, cmus when the music stops, play, ogg123, playsound).

I get this in /var/log/errors.log

Found a bug on alsaproject (not very helpful though)

@Romashka: I think this is different from 6978: there the card is hda-intel, ours is AC 97/ali5451. There was no sound, we get sound, just messed up.

Back to normal with kernel 2.6.21.3-1 and new alsa packages (1.0.14rc4-1). Kernel gives exactly the same error messages (dmesg and errors.log) as before, but sound works again. Makes me think the problem was with alsa-lib. Confirmed by 2 more people on abovementioned forum thread.
