ALSA doesn't recognize the internal microphone on Eeepc 901. I have a "Mic
Boost" setting in the alsa mixer, but nothing like "i-mic", or anything else to
enable recording from microphone.
One part of /proc/asound/card0/codec#0 (full content in attachment) appears to
be strange:
===8<===
Node 0x12 [Pin Complex] wcaps 0x400001: Stereo
Pincap 0x00000020: IN
Pin Default 0x99a30920: [Fixed] Mic at Int ATAPI
Conn = ATAPI, Color = Unknown
DefAssociation = 0x2, Sequence = 0x0
Misc = NO_PRESENCE
Pin-ctls: 0x20: IN
===8<===
Are there any kernel boot parameters or hwdep configs to try to work around
this bug?
