Public bug reported:
Binary package hint: linux-sound-base
I upgraded the kernel today, now I have no sound.
I used to use pulseaudio, so I switched back to alsa in any case, but no
chance.
Everything looks OK, no application complains about the sound, I can use
the sound mixer, etc. Just no sound in either the high speakers or
through earphones.
At boot, I can hear the "click" when the sound card is activated.
I followed the "Sound Troubleshooting" wiki page but it was no help. I
just have to boot on the 2.6.24-3 kernel to have sound back.
I suppressed my ~/.asoundrc* files with no change.
I filed the bug against linux-sound-base, but it's only a guess.
