Summary:                    No Sound, No error message,
Description: 
Installed new Kernel 2.6.16.9 and put ALSA 1.0.11 (compiled from source) on
it. Made alsalib and alsautils to the same version 1.0.11. No error
messages, no error in alsaconf, all rulers in alsamixer on full, but no
sound. Even cat <something> > /dev/sound/pcm... causes no noise (otherwise
I would assume that something is wrong with my KDE artsd). Sound HW OK
because it is perfectly running under Windows and Solaris on the same
machine. See attached aadebug output.

Question: How to analyse further

Thanks for ur support

I have the exact same problem. Occurs on 2.6.17-rc3 with -mm1 patch, but
not with 2.6.16. aadebug output attached with name "aadebug-output"

Actually, on further investigation, it turns out I was forgetting to unmute
the PCM. I was just turning the volume up to 100, and didn't realize that
it was still muted. I unmuted the PCM and it works fine now.

To the original reporter, try this:
# amixer set PCM 100 unmute
