From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040625 Description of problem: During the firstboot, system-config-soundcard failed to test sound on Dell Precision 650n (integrated AC'97 Audio Controller) Version-Release number of selected component (if applicable): system-config-soundcard-1.2.8-1 How reproducible: Always Steps to Reproduce: 1. Install a fresh FC3 Test 1 2. Follow Firstboot steps 3. system-config-soundcard failed to test sound on Dell P650n due to it set PCM-2 channel to 0 by default. No sound can be heard during the sound testing. Actual Results: It was necessary to run volume-control and set PCM-2 channel to about 80% in order to hear test sound for system-config-soundcard. Expected Results: It should have set PCM-2 channel to about 80% during the firstboot step in order to hear test sound for system-config-soundcard. Additional info:
This line in the /etc/modprobe.conf should have unmuted the sound: install sound-slot-0 /sbin/modprobe --ignore-install sound-slot-0 && { /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :; } Could you try: 1) Remove the driver from the kernel with rmmod 2) Remove (or move away) /etc/.aumixrc 3) Launch "modprobe sound-slot-0" and check that the mixers are unmuted
It seems the actual entries in /etc/modprobe.conf is different than what you've described. Please see modprobe.conf from: http://fedoranews.org/tchung/fc3-test1/bug/ Notice, lsmod shows 'snd_intel8x0' but modprobe.conf shows 'snd-intel8x0' Could this be a typo? Also it did not create /etc/.aumixrc file since it's using /usr/sbin/alsactl instead of /bin/aumix-minimal I've also included some screenshots which shows, 'volume-control-tab1.png' PCM-2 channel is set to 0 by default and this is why I could not hear any test sound during the firstboot steps.
I've added some code to unmute PCM-2 as well. Will be in rawhide soon (ie. after the freeze). (you can try and copy the code that sets Master and PCM, and add a "PCM-2" case yourself to soundcardBackend.py, if you want to test this).
