There are "Mic Boost" and "Front Mic Boost" mixer volumes.
Not with model=laptop-eapd - my alas mixer only shows Master, PCM, Mic, Capture, Mix, External Amp and Internal Amp
The Mic Boost control was added _after_ 1.0.14 release. (Correction in the above text: Front Mic Boost doesn't exist for AD1986A but for other codec.)
So, please try HG version first. Then let's debug further.
Note that the auto-mute feature isn't implemented yet in HG version, too. But the mic boost should work at least.
I downloaded the HG version, compiled against my kernel and re-loaded just the modules ( so as not to break too much else ). I get the two microphone boost controls ( one for playback and another for capture ) and they work. I can record from both internal and external microphone.
The `Internal Mic.' bar/switch appears to do nothing
The `Microphone" bar/switch is active and behaves as expected
I see a couple of extra modem related controls ( Caller ID and Off-hook ) - does that mean I can make the soft modem ( Si3054 ) work with slmodemd --alsa ???
Still no PC speaker ....
The below is the untested patch for adding the auto-mute feature. A new model laptop-automute is implemented. Of course, it's against the latest HG version. Give it a try.
I tried applying the automute patch but I must have picked the wrong version of pci/hda/patch_analog.c because most of the patch failed. At what stage was the patch supposed to be applied ? I did it after having done all the steps on the devel page.
