From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041020 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 alsamixer. 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): kernel-2.6.10-1.737_FC3 How reproducible: Always Steps to Reproduce: 1.boot kernel-2.6.10-1.737_FC3 on an IBM ThinkPad T40 2.try to play a sound 3. Actual Results: no sound heard Expected Results: hearing sound from speakers / headphones Additional info: I will attach dmesg + lsmod output from both the working and the troublesome kernel versions.
Created attachment 109662 [details] dmesg output for 2.6.10-1.737_FC3 (where the problem occurs)
Created attachment 109663 [details] lsmod output for 2.6.10-1.737_FC3 (where the problem occurs)
Created attachment 109664 [details] dmesg output for 2.6.9-1.681_FC3 (where sound works fine)
Created attachment 109665 [details] lsmod output for 2.6.9-1.681_FC3 (where sound works fine)
Note: 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. Philippe
