alsamixer missing controls

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have a system here where alsamixer does not list all of the controls
(specifically the one controlling which of the two analogue inputs is
sampled when recording happens, "Mic Capture Switch").  The control is
listed in the file that "asoundctl store" creates, and altering the
value and then issuing "asoundctl restore" does successfully manipulate
it.

It's not in any of the tabs (Playback/Capture/All) in alsamixer.  Does
alsamixer not display all controls by default?  If so, how does it make
this decision?

state.tlv {
	...
        control.4 {
                comment.access 'read write'
                comment.type BOOLEAN
                comment.count 1
                iface MIXER
                name 'Mic Capture Switch'
                value true
        }
	...
}

Thanks for any insights!
