internal mic auto mute

M

mdg583

info snd_hda says:

Code: 
The sequence number 15 has a special meaning for output associations.
Output pins with this number and device type ``Headphones'' will duplicate
(with automatic mute if jack detection is supported) the first pin in that 
association.

Woudln't it be nice if device type 'mic' could do the same? So that when you plug in an external microphone, it mutes any internal microphone you might have.

Or is there a way to do this?

If I'm not mistaken this already happens.
 
Unluckily, it is not described in UAA specification. Sequence 15 for input associations has different meaning, choosing between mixed and switched input modes, which is not needed for snd_hda.
 
So i am also curious about this, for the moment after alot of work with device.hints i got the sound to work. But the mic/mix is getting sound from both internal mic in the monitor and the external one at the same time

Recording source:

Anything i am missing?
 
You should choose recording source. It was a bug when default selection was undefined. Recording from monitor and mic should give you separate sources, mix will give you both.
