[alsa-devel] HDA Intel/ALC269 microphone problem

[Mathieu Bouffard]

Read a few bug reports (going back to 2009!) around where users couldn't 
use their microphone with HDA Intel/ALC269. I had one set up JACK for 2 
playback channels and 1 capture channel, make an .asoundrc to route 
everything to pulse which is started with a configuration only using 
module-jack-sink and module-jack-source, start it up and the microphone 
and the whole setup worked. But that's quite a hassle for a workaround!

I had suspicions that it was the stereo mic causing problem and forcing 
mono would work and it seems to be the case. I attached a patch, hoping 
that the fix might be as simple as forcing mono at the ALSA level, but I 
don't think it'll be that simple... Can someone more experienced see if 
more is needed, and if not then commit it?
