why do you say the internal mic is mono ?
do you mean only left channel has signal or left and right channel out of
phase ?
if the default Amp-In , the control should be a internal mic boost instead
of internal mic capture volume
the capture volume control is at node 0x17 which support R/L (swap of left
and right channel)
Default Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0
Node 0x11 [Pin Complex] wcaps 0x400483: Stereo Amp-In
Control: name="Internal Mic Capture Volume", index=0, device=0
ControlAmp: chs=3, dir=In, idx=0, ofs=0
Amp-In caps: N/A
Amp-In vals: [0x01 0x01]
Pincap 0x00000024: IN Detect
Pin Default 0xd5a30130: [Both] Mic at Int Top
Conn = ATAPI, Color = Unknown
DefAssociation = 0x3, Sequence = 0x0
Misc = NO_PRESENCE
Pin-ctls: 0x20: IN
Unsolicited: tag=00, enabled=0
Power: setting=D0, actual=D0
Node 0x17 [Audio Selector] wcaps 0x300d0d: Stereo Amp-Out R/L
Control: name="Capture Volume", index=0, device=0
ControlAmp: chs=3, dir=Out, idx=0, ofs=0
Control: name="Capture Switch", index=0, device=0
ControlAmp: chs=3, dir=Out, idx=0, ofs=0
Amp-Out caps: ofs=0x10, nsteps=0x2e, stepsize=0x03, mute=1
Amp-Out vals: [0x11 0x11]
Power: setting=D0, actual=D0
Connection: 6
