Description Chris 2007-07-29 01:37:06 UTC
Description of problem: When I first start up and login, there is only sound coming out of one channel. Until the volume slider is moved, it is stuck like that. Once the slider in the mixer is moved, sound comes out of both left and right channels. Version-Release number of selected component (if applicable): 1.0.14-0.4.rc3.fc7 How reproducible: Happens every time I start up the computer and login Steps to Reproduce: 1. Start up and login 2. Play something and listen to sound 3. Move the volume slider and listen again, sound is now stereo Actual results: Sound is not stereo until slider is moved. Expected results: Sound should always be stereo since the channels are linked and they are not muted. Additional info:

Here is a link to Launchpad report, as I had this problem in Ubuntu Feisty as well. They have linux-source-2.6.20 marked as the affected package, but since Fedora 7 uses 2.6.22.x that needs to be changed. https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/110481

Aha, okay. There's an updated kernel package for F7 with alsa-drivers 1.0.14. Anyway, what channel do you have to move? There's a command line utility nammed alsaunmute what should set all channels to the default values. Does it do that? Anyway, can you please attach /root/scsconfig.log? It can be generated by system-config-soundcard.
Comment 4 Chris 2007-08-17 05:57:00 UTC
The channel I have to move is "PCM". I ran the command "alsaunmute 0", and that made the volume louder and unmuted the left channel. However it doesn't work if I reboot, I have to do it again just like moving the volume slider.
Comment 5 Martin Stransky 2007-08-20 11:18:32 UTC
Aha. Is the volume of "PCM" preserved during boot? If not, that could be a dupe of Bug 247468. Anyway, please report it at upstream (www.alsa-project.org) and file a bug there. This bug should be fixed there for all distros.
Comment 6 Chris 2007-09-19 21:53:10 UTC
Hi Martin, sorry for the delayed response. The PCM level isn't preserved when I reboot, it goes back to 50%. I believe with the updated alsa-drivers, that the stereo problem has been taken care of, so this bug can be closed and set to fixed. I will contribute to Bug 24746 to help with that one. Thanks for all your help!
