What is the highest os for macbook air model a1237 mac osx#
You have to figure it out by digging some Mac OSX stuff.Ĭontrol: name="Mic Boost Volume", index=0, device=0 If any of the above hits nothing, there must be vendor-specific verbs like COEF setup. The GPIO 1 isn't currently used, so this might hit something interesting. You can confirm it by changing it dynamically. The GPIO 0 seems already used for the speaker (and/or HP) amp. The call with GET_PIN_SENSE would return the bit 0x80000000 if the jack is detected.Īnother item to test is the GPIO pins. % hda-verb /dev/snd/hwC0D0 XXX GET_PIN_SENSE 0 % hda-verb /dev/snd/hwC0D0 XXX SET_PIN_SENSE 0 It might not have a dedicated jack detection since it's a TRRS. Test always a stereo stream, not a mono.Īlso, another interesting test would be to check the pin-detection for the external mic. You can fiddle with different VREF values of the pin on the fly via hda-verb, too.įor primary testing, better to avoid PulseAudio although it shouldn't interfere too much in this case. Also, make sure that the pin control of the corresponding pin is set property to input (at least bit 0x20 is set). At each time, check the mixer setup ("Capture Switch" is unmuted, "Capture Volume" is raised, etc). Test both the built-in mic and the external mic jack for each pin. Try even the HP or the speaker pin to replace as a mic. You need to test the all pins from 0x14 to 0x1f, one by one. still told me it was more similar to a HP than a Mic, so I also discarded the hypothesis of installing ArchĪny other number combination I could try to pass?

Strange that the driver created headphone mic at node 0x15
