Hello everyone who is interested in helping me solve my volume control problem!
Lets see, I have sound playback working, currently I am listening to some Foo Fighters mp3s in XMMS using the Alsa plugin, so I can't complain too much.
However, volume control doesn't work. If I set the alsa plugin to use software volume control, then I have volume control but its not ideal and it doesn't help me when I'm not using xmms. When I run alsamixer or open the gnome volume control, I have multiple volume controls for the "Speaker" device. The 1st pair of volume controls do nothing, I can mute them and my music keeps playing... no idea what they're controlling. The 2nd pair ("Speaker 1") DOES control the sound volume. I just need to find a way to remap it or something so I can configure my applications/tray icon/etc to use it. (And preferabbly not the other 6 channels)
In the Gnome sound control, the devices are:
"Speaker" - stereo control that doesn't do anything
and "Speaker 1" - a 7.1 channel (8 sliders) with the first two controlling front left and right sound for my stereo speakers.
I've tried setting xmms to use "speaker 1", but the option is not in the drop-box, tried typing it manually but that didnt work.
I set my tray icon to control "speaker 1" but the sliders don't seem to lock properly and the volume just jumps around, unlocking the channels and not staying balanced or scaling with the slider.
The only way to get the volume to change as expected is to open the gnome volume manager, make sure the channels of "Speaker 1" are UNLOCKED and slide the first 2 sliders to the desired volume.
So I was thinking if I could just remap the first two channels of "speaker 1" to something else using an alias or link or editing asound.state (which just confused me) for example, then I could use my alias to control the sound in my applications. Thanks for any help with this!
Here's some system info that may or may not help:
