[Touch-packages] [Bug 1410618] Re: MacBook Air 6, 2 TRRS Headset Mic Not Working
Having the same problem with a 2017 12” Macbook (the Macbook10,2). The microphone shows up as “(unplugged)” in pavucontrol and pacmd regardless of if I have the headset plugged into the combo jack or not. Headphones are detected and work. The internal mic is still accessible and the Microphone input seems to be mirrorring it (could be to do with some chip-level switching that somehow doesn’t happen on Linux?). I’ve tried inputting all choices of model available in the CS4208 quirk list for PulseAudio (there isn’t one for my particular model) into alsa-base.conf and nothing has changed (having nothing in alsa-base.conf, which I did before attempting this fix, also makes no difference). I’m running Debian 10 with kernel 4.19.0-17-amd64. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1410618 Title: MacBook Air 6,2 TRRS Headset Mic Not Working Status in alsa-driver package in Ubuntu: Confirmed Bug description: 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.

Unfortunately I was never able to solve this. It appears the Windows issue (referenced above) remains as well. Maybe an examination of the Apple/OSX driver (if that's even possible) would lead to a solution here. As a work-around I purchased a small USB sound card and plugged into that. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1410618 Title: MacBook Air 6,2 TRRS Headset Mic Not Working Status in alsa-driver package in Ubuntu: Confirmed Bug description: 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.

[Touch-packages] [Bug 1410618] Re: MacBook Air 6, 2 TRRS Headset Mic Not Working
So it looks as if the bug that generated that commit was due to no sound coming out of the air's speakers and there's really not much talk about the TRRS mic-in functionality: https://bugzilla.kernel.org/show_bug.cgi?id=60811 That commit may be responsible for the working sound and headphone detection - but there may be more work to do in order to get the TRRS mic working. Likely why installing the latest ALSA driver isn't changing anything with regard to the mic. sudo hdajacksensetest -c 1 prints out: Pin 0x10 (Grey Headphone, Left side): present = Yes Anyway it sounds as if the pin configuration introduced in that patch was gleaned from a Windows inf driver file back in 2013.

Interesting - that commit does appear to target my machine specifically, and contains a pin configuration for it: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b5bf0a929d7ca35b9ccfc24647a397899d307659 Oddly, when I upgraded the ALSA driver to the latest as that wiki page outlined, there was still no trace of the headset mic when plugged in.

Hi chrisolof, 1) hdajacksensetest shows the result of the HDMI graphics card, you probably want to add "-c 1" or similar to get the analog card instead. 2) Looking at your alsa-info, it seems like somebody has already tried to improve the driver for your card.
