<pre wrap="">Dear list,
I am running FC7, kernel 2.6.23.17-88.
It has been fine for more than 2 years.
Yesterday, the audio stopped working.
I thought it was the HW.
I booted into WinXP and tested the audio,
Audio was fine.
How do I debug this problem to find out the cause?

Well Fedora core 7 is old, but I'm posting from Fedora core 2, so as far as
I'm concerned, if it is still working, and your happy with it, keep using it.
Back to your sounds. Can you post the output from the following commands,
which will show if the soundcard is being detected, and if the necessary
modules are being loaded,
cat /proc/asound/cards
/sbin/lsmod | grep snd
It's worth also opening alsamixer in Gnomes terminal, or KDE's Konsole, if
you're using KDE like me, and see if all the necessary sliders are still up
(Master, Front, PCM, CD), and that none of these controls are muted (The M
key toggles the mute/unmute).
Have you plugged a new audio related device into the USB (webcam, usb midi
keyboard, etc). The usb starts early in the boot process, and alsa can detect
these devices as soundcards, and set them as card0, thus stopping your actual
soundcard using the card0 slot, resulting in no sounds.
Just a few thoughts for a start.
Nigel.

The only NEW item I have plugged in over 2 weeks ago has been<br>
a BLUETOOTH stick for my bluetooth mouse. But that did not disable<br>
the sound. The sound went away about 2 days ago. So, That leaves<br>
me puzzling over why I lost the audio.<br>
