I am using FC3 on ThinkPad R50e. I had sound problems earlier while upgrading the kernel. The solution on the below given URL solved the purpose: http://www.ces.clemson.edu/linux/alsa.shtml Now yesterday suddenly while using my ThinkPad volume keys sound stopped responding, I have tried the same solution no help. I have disabled the 'tpb' as well. Sound is not responding. I looked into Bug 144742 and related, but no solution worked. Presently I have set snd_intel8x0m in /etc/hotplug/blacklist . https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=144742 My sound card information is as below: 00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) Think Pad R50e 1834 RYV76 with kernel 2.6.10-1_760 FC3 Please suggest. -- Kevin Verma <kevinverma@xxxxxxxxx>
