Description of problem: The sound Fedora 10 outputs to the speakers is very faint. I can get up to barely usable volume only by maxing out every slider (after turning them all on) in volume control. Strangely I couldn't hear anything at all until I also maxed out the side channel. Also, plugging in headphones does not mute the speaker as it should. These problems were not present in Fedora 9. Version-Release number of selected component (if applicable): uname -a Linux tyr.ragnarok 2.6.27.9-159.fc10.i686 #1 SMP Tue Dec 16 15:12:04 EST 2008 i686 i686 i386 GNU/Linux rpm -q pulseaudio alsa-lib pulseaudio-0.9.13-6.fc10.i386 alsa-lib-1.0.18-6.rc3.fc10.i386 How reproducible: Very. Steps to Reproduce: 1. Boot the computer. 2. Run rhthymbox 3. Listen to music Actual results: Music faint even with all volume levels maxed out. Expected results: Normal control over music volume.

Mea culpa. I hadn't noticed there are two analog outputs and must have switched them when I installed Fedora 10. I guess one is center and the other is a side channel. Switching my to the other analog output fixed all my problems.
Closing then. Hopefully in one of the versions of Fedora we will have a more complete mixer default initialization database which will set these things up correctly by default.
