Description of problem:
I get no sound from my builtin soundcard.
Sound works fine when I reboot with kernel-2.6.9-1.681_FC3
I am using ALSA, driver snd_intel8x0
I did make sure the volume controls are not muted, with both aumix and
xmms & other applications behave like they are playing, but I get no
sound from the soundcard. Works fine with kernel-2.6.9-1.681_FC3.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot kernel-2.6.10-1.737_FC3 on an IBM ThinkPad T40
2.try to play a sound
Actual Results: no sound heard
Expected Results: hearing sound from speakers / headphones
I will attach dmesg + lsmod output from both the working and the
troublesome kernel versions.

I have experienced the same problem with 2.6.10-1.8_FC2 on Fedora Core 2.
Same problem here on a ThinkPad T41p.
This problem also occurs on my Toshiba Satellite. Just commenting to
confirm the problem.
I confirm the problem on the thinkpad T41p
Same problem on internal AC97 sound with x86_64 with new 2.6.10. Ok
with last 2.6.9.
FC2 : 2-6-10-1-8
It seems to be an old problem ... following me from time to time, from
kernel to kernel. I never had clear answer but this seems to be linked
with AC97 and/or Ensoniq card.
My bypass is :
- booting with a new kernel .. no sound.(often)
- trying : System setting / Sound card detection
---> result can be OK or KO. If OK, no need to reboot.
- rebooting same new kernel
- sound is here or can be activated bu Souncard Detection
It works 80% of the time.
