[alsa-devel] Macbook Air 2,1 - no mic nor main speakers
Hello list, this came up a year ago and Takashi's answer was "a broken bios". I was hoping someone here could point me to documentation to read in order to diagnose the problem if indeed is a broken bios. I don't want to start randombly reading the driver's code.
Macbook Air 2,1 2.6.32-gentoo-r3 SMP x86_64 Alsa Driver 1.0.21 libs 1.0.22 nVidia Corporation MCP79 High Definition Audio (rev b1) HDA NVidia at 0x93380000 irq 19 00:08.0 0403: 10de:0ac0 (rev b1) Subsystem: 10de:cb79 Codec: Realtek ALC889A
Booting with snd_hda_intel.model=mbp3 get sound on headphones, but not on mainspeakers. The mic never worked.

Hello again, I found out that puting the pin in 0x18 as a PIN_OUT I get sound in the internal speaker. Currently I can change patch_realtek.c to load the driver using an "mba21" model and I get sound on the main speaker. One of the (many) problems I have is that I need to use something like
{0x18, AC_VERB_SET_PIN_WIDGET_CONTROL, (PIN_OUT | AC_PINCTL_VREF_50) }
otherwise it goes into HiZ and I get no audio. Looking at that patch_realtek.c I don't see anything similar. Anyway, I don't have a clue about ALSA, I just started reading the HDA specification and looked over patch_realtek.c and came up with the small change below to have a working main speaker. I'd appreciate if you had any suggestion for the mic or to point me towards the right documentation.
Sincerely,
R.

The change looks almost good -- except for one place.

- static void alc885_mba21_setup (struct hda_codec *codec)
- {
- struct alc_spec *spec = codec->spec;
- spec->autocfg.speaker_pins[0] = 0x18;
Does this device have no dedicated headphone output pin? Usually it's either 0x14 or 0x15.
Also, please make a patch in a unified diff format.
If the patch is ready for merge, please post it (and add me to Cc) with a proper changelog and your sign-off.

The headphones are in 0x14 but I couldn't get them to shut the main speakers off yet when the hp jack is connected. As soon as I understand how the other examples in patch_realtek.c work and get this working I'll send you a working patch.

Then check rather whether the pin 0x18 is really the right pin for the speaker output. This can be checked easily via hda-verb or so. The speaker can be 0x15 and/or 0x1a, instead.

The patch below is the best I can do without loosing my day job :) with this patch I get audio on main speaker letting it be 0x18. At the same time if I put 0x14 to be the hp pin I get it to mute the main speaker whenever I plug the jack, but I can't get audio from the hp.
The funny thing is that in mbp3 mode I get audio from hp but not from main speaker. Interestingly enough, if I start with mbp3 mode and run hda-analyzer, the switching pin_out in 0x14 decides whether or not there's output in the hp and switching pin_out in 0x18 decides wether or not there's output in the main speaker.

Attached is a patch in unified diff format that adds support for Macbook Air's 2,1 internal speaker and headphone. Only one mixer control for both, but at least the main speaker mutes when the jack is connected and the headphones work fine now (at least in my machine). I couldn't find the mic yet. I do not know what a proper changelog is nor what my sign-off would be, I do mathematics for a living (or so I thought).
I'll update the bug I opened over a year ago when I didn't know about hda-analyzer.
Cheers,
