Hello,
I'm running Ubuntu Gnome 14.04 on a new MacBookAir6,2 with the Cirrus
Logic CS4208 and would love to get the microphone part of the TRRS
connector working. Mac OS picks up and utilizes the TRRS headset mic
without issue so I know the hardware is a go.
Running sudo hda-jack-sense-test -a results in:
Traceback (most recent call last):
File "/usr/bin/hda-jack-sense-test", line 47, in <module>
codec = HDACodec(cardindex, codecindex)
File "/usr/share/snd-hda-tools/hda_codec.py", line 1036, in __init__
self.parse_proc()
File "/usr/share/snd-hda-tools/hda_codec.py", line 1135, in parse_proc
self.proc_codec = HDACodecProc(self.card, self.device, file)
File "/usr/share/snd-hda-tools/hda_proc.py", line 479, in __init__
self.parse(proc_file)
File "/usr/share/snd-hda-tools/hda_proc.py", line 677, in parse
node.add_digital(line[11:])
File "/usr/share/snd-hda-tools/hda_proc.py", line 296, in add_digital
self.wrongfile('unknown dig1 bit %s' % repr(b))
File "/usr/share/snd-hda-tools/hda_proc.py", line 143, in wrongfile
raise ValueError, "wrong proc file format (%s)" % msg
ValueError: wrong proc file format (unknown dig1 bit 'KAE')
So not really sure where to go from here. I opened up hdajackretask to find
four pins:
Green Headphone
Pin ID: 0x10
Headphone
Internal Speaker
Pin ID: 0x12
Internal speaker
Pink Mic
Pin ID: 0x18
Not connected
Internal Mic
Pin ID: 0x1c
Internal mic
Unplugging and replugging the headset changes the Output device in sound
settings from Headphones to Speakers so that works, but nothing in the
input tab ever changes. It always lists two devices: Internal
Microphone and Microphone. Both of these seem to actually be the
internal microphone in the mac - either works without the headset
connected at all.
So I'm not really sure how to proceed from here, but I'd be happy to run
whatever diagnostic tests might prove useful and/or even contribute code
toward a fix - but I just have no idea where to start. Is it as simple
as just finding the right pin and telling the system to use it as a
microphone?
