Hi

I would like to record sounds and use voice chat. In the previous version, I would change the input source from mic to front mic to do this.

The new GNOME volume preferences in Fedora 11 doesn't expose all the ALSA controls. This is discussed in many places including:

https://bugzilla.redhat.com/show_bug.cgi?id=491372

https://bugzilla.redhat.com/show_bug.cgi?id=495148

I tried pavucontrol and it doesn't seem to allow me to set the input source either. I had to install xfce4-mixer to finally get this. What is the recommended solution here?

Have you read the discussion in the bugs you are pointing to ?

I glimpsed through it and I don't see a current solution to the problem. If I missed something, let me know. I need to update the release notes.

https://bugzilla.redhat.com/show_bug.cgi?id=491372#c9

and

https://bugzilla.redhat.com/show_bug.cgi?id=491372#c13

Give a good summary of the current state.

In short: Alsa in its current state doesn't allow to implement a useful input selection UI. All you can currently do is expose Also controls 1-1 in the interface. alsamixer -c0 does that sufficiently well.

I could suggest using alsamixer as a workaround for now except that I couldn't figure out how to switch between mic and front mic in alsamixer. Any pointers?

No. Using alsamixer -V capture might make things a little easier.

Tried that already. alsamixer -V capture gives me a single control to move up or down. It doesn't allow me to switch between mics and I have to use kmix or xfce4-mixer (both of which have a long list of dependencies, some of which are odd ) to actually do what I want.

I tried alsamixer -V capture -c0 gives me more controls but front mic is disabled with no way to adjust that setting. Not sure whether there is any better solution and telling users to install other desktop environment's volume control doesn't seem right. Open to ideas.

man alsamixer lists available keyboard commands. 'm', space, up and down seem good candidates for randomly hitting.

#amixer -c 1 sset front cap

That just returns the help back to me but it looks like I found the answer

# amixer -c0 sset 'Input Source' 'Front Mic' Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Mic' 'Front Mic' Item0: 'Front Mic'

Thanks for the hint.
