What seemed to be a simple little task of getting the microphone to work, ended up becoming a bigger task than I had set out. (oh-well, good learning experience).
Anyways below you will find an updated patch to the iMac9,1 machine which fixes some issues that I found.(keep in mind this is still a work in progress).
First issue: With the original patch, I've noticed by unmuting the mic (and even having it muted), there is a distorted("Noise") coming from the internal speakers, even when the headphones are plugged in. What my finding's revealed is:
/* Mic (rear) pin: input vref at 80% */ {0x18, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_VREF80}, {0x18, AC_VERB_SET_AMP_GAIN_MUTE, AMP_OUT_MUTE},
From the original patch. Looking at codec#0 0x18/0x1a is listed as:
Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0 Amp-In vals: [0x00 0x00] Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x00 0x00] Pincap 0x0000373c: IN OUT HP Detect Vref caps: HIZ 50 GRD 80 100 Pin Default 0x90100141: [Fixed] Speaker at Int N/A Conn = Unknown, Color = Unknown DefAssociation = 0x4, Sequence = 0x1 Misc = NO_PRESENCE Pin-ctls: 0x41: OUT VREF_50 Unsolicited: tag=00, enabled=0 Connection: 5 0x0c* 0x0d 0x0e 0x0f 0x26
seems this Node is listed as: [Fixed] Speaker while 0x15
Node 0x15 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0 Amp-In vals: [0x00 0x00] Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x80 0x80] Pincap 0x0000373c: IN OUT HP Detect Vref caps: HIZ 50 GRD 80 100 Pin Default 0x018b3020: [Jack] Line In at Ext Rear Conn = Comb, Color = Blue DefAssociation = 0x2, Sequence = 0x0 Pin-ctls: 0x01: VREF_50 Unsolicited: tag=00, enabled=0 Connection: 5 0x0c 0x0d* 0x0e 0x0f 0x26
is [Jack] Line In at Ext Rear. (looking at the other apple products as examples I came up with the fix below).
Second issue: alc885_mbp_4ch_modes The original patch does a good job with the HP pin automute function, but from what I noticed is I would have to manually change the channel form 2 to 4 after plugging the headphones in. And not to mention having odd moments to where I was jamming out with the headphones on, then later realized I had sound blasting out of the speakers as well. My findings revealed that changing alc885_mbp_4ch_modes to alc885_mba21_ch_modes and setting
- spec->autocfg.speaker_pins[0] = 0x15;
- spec->autocfg.speaker_pins[0] = 0x18;
gets the automute function when the headphones plugged in working flawlessly(and the no need to manually change the channel number afterwards).
Third issue: alc885_imac91_mixer There probably doesnt need to be anything changed with this (esspecially if your one to like lots of sliders),but my findings revealed that mac osx only has a master on the top right, another switch on itunes, and then a slider for the mic.
So the changes I did below try and mimic osx as much as possible (only thing I had an issue with is just having one mute switch on the master, instead of having two(still investigating)).
fourth issue: alc882_capture_source I endeded up creating alc889A_imac91_capture_source() only because looking at alc882_capture_source I see that the mic is set to 0x1 while this works, I also noticed that adding 0x1 and 0x01 and testing that 0x1 somehow stops working, and 0x01 works(so I figured 0x01 was more of the alpha of the numbers(still need to figure out where that valuse is)). In any case the microphone does work with the original, and with the below patch, but both still record not as clean(lots of "Noise", which I would like to look into too). Note: using alsamixer -Va reveals the capture switches.
Overall the original patch is good, the below patch does (hopefully)address some issues, if it's too much of a change I can go back, and just adjust the verb pins on the original and just call it that..(main thing over here is I don't have the "Noise" coming out of the speakers(and music sounds good)...
cheers..

Looks good. Now applied. Thanks.
