Faint sound and and headphones problem
Last modified: 2009-01-12 12:16:15 EST
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):
Linux tyr.ragnarok 18.104.22.168-159.fc10.i686 #1 SMP Tue Dec 16 15:12:04 EST 2008 i686 i686 i386 GNU/Linux
rpm -q pulseaudio alsa-lib
Steps to Reproduce:
1. Boot the computer.
2. Run rhthymbox
3. Listen to music
Music faint even with all volume levels maxed out.
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.
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.
