Patch without space removal

Thanks for the patch.
Could you give alsa-info.sh output (run it with --no-upload option), too?

Also, for including into the upstream, we need your sign-off.
See Documentation/SubmittingPatches section 12 for details.

Patch with signed-off

this also effects Macbook Pro 11,2 (and probably 11,3)

Thanks.  Looking at alsa-info.sh output, the pin configs appear sane.
Do you really need to override the pin configs with mba6?
That is, isn't it enough to set up GPIO (i.e. using CS4208_GPIO0 instead of CS4208_MBA6)?

In other words, does the patch below work instead of yours?

alsa-info without patch

Ignore the rc5 kernel name, it contains the patch for MBA.

It works with GPI00 patch !

OK, then also check whether all components work properly.
The machine seems to have a bass speaker, and whether the corresponding mixer control really changes its volume.  Also BIOS shows that there is a digital output, independent from HDMI.

Hello, I have a macbook 11,3, applied the patch, now the speakers work, but not the bass speaker, anything I can do to help?

my alsa-info http://www.alsa-project.org/db/?f=1ef574f441eca35eead9f0d8d76ebd6a71344fd4

Try to pass model=mba6 option to snd-hda-intel module.  Then the pin configuration for MBA6 will be used instead of BIOS setup.

nope, now the bass speaker control in alsamixer disappeared and it's worst than before.

I should have mentioned that without the model=mba6 option, the bass speaker controls did something, although I don't know if it's activating the subwoofer, if I lower it down to 0, the bass goes away, but cranking it up to 100% it just doesn't sound the same as in OSX, very little bass output.

Takashi Iwai: "Also BIOS shows that there is a digital output, independent from HDMI."

Could this be the digital audio output (optical SPDIF) that is combined into the headphone port? (the light for mine is actually stuck on 'amixer set IEC958 off' doesn't turn it off for me like it did on previous models)

The most recent patch does enable the speakers on Macbook Pro 11,2 (the Oct 2013 version). However, the mute button doesn't work.

If bass speaker produces any output, it's likely working as expected.  Just check whether the amp is set to full on the corresponding pin.  So I applied the patch in comment 9 now to sound git tree.

The soft bass output is probably the software issue, not the hardware (device driver) issue.  MacOS may be modifying the PCM stream to enhance the bass.

Regarding the digital output: yes, this can be an SPDIF, if it exists.  There are multiple IEC958 controls (HDMI outputs have the same named controls, too), so a simple "amixer set IEC958 off" might not work.  You'd need to specify the exact index, device, etc.

About the mute button: this isn't what the sound driver serves.  Usually the mute key is handled as a normal input key event, and your desktop system should react to it and change the mixer appropriately.  For that, usually you'd just need to adjust the keymap in udev (or systemd) to assign the corresponding key code to AudioMute key symbol.

Bass speaker seems to work (even though PulseAudio doesn't seem to do anything with it automatically).

Still trying to figure out how to power off the optical output (SPDIF?)

Try to turn on/off "IEC958 Playback Switch" via alsamixer.  Run "alsamixer -c0" (or -c1, depending on the PCI slot).

If this doesn't help, please give alsa-info.sh outputs with both IEC958 on/off states.  (Better to run alsa-info.sh with --no-upload option and attach the outputs to this bugzilla.)

muting all spdif in alsamixer -c0 and alsamixer -c1 does not turn the optical audio off

Looks like your kernel isn't fully patched.  The codec name appears "Cirrus ID 4208".  With the fully patched kernel, it must be "CS4208".

But the SPDIF issue might be independent from that, judging from the alsa-info.sh outputs.  The mixer switch actually turns off IEC958 status enable bit, so it works as expected.  But it doesn't seem to influence on the SPDIF light.

I guess the SPDIF red light is always on even if you pass model=mba6 option, right?  (I know it breaks other things, just to check about the SPDIF.)

If so, the only possible control, except for secret vendor-specific verbs, is to power down the converter.  Try like:
    hda-verb /dev/snd/hwC1D0 0x0e SET_POWER_STATE 0x03

Does it turn off?  If yes, does the following recover?
    hda-verb /dev/snd/hwC1D0 0x0e SET_POWER_STATE 0x00

hi, model=mba6 did not seem to turn the light off.
however, those two hda-verb commands both worked.

OK, what about this?  For light off,
    hda-verb /dev/snd/hwC1D0 0x21 SET_PIN_WID 0x00
and for light on,
    hda-verb /dev/snd/hwC1D0 0x21 SET_PIN_WID 0x40

yes, those two both worked

The patch in comment 9 turned out to break the existing MBA6 fixup.
The additional patch is attached below, in order to make MBA6 working again.

Also, judging from the information in comment 28, the SPDIF light can be controlled via the pin control value.  The patch to add the support is attached below, too.

Give them a try.

Success.  Sound is working and I can turn the SPDIF light off and on with the IEC958 switch.

Combined patches for complete fix against linux 3.12

Could the following line also be added for Macbook Pro 11,3

SND_PCI_QUIRK(0x106b, 0x5e00, "MacBookPro 11,3", CS4208_MBA6),

Agh ignore that just realised IDs are the same. Maybe the 3 should be dropped or a comment added that it covers all of them?

I can also confirm that the patches from #30 and #31 fix MacBookPro11,3

The patches have been merged and will be included later to Linus tree.  It should be in 3.13-rc1.

Dear all,
I want to need your builded fruitful patch, but I don't know patch destination.
I need sound output MBP13 for ubuntu. If you can any advice to me, I am so happy.
I am so sorry, please let me know patch method.
Sincerely regards,
Kazumichi Aoki,

Dear all,
I miss understanding this problem. I have fix that.
Thank you so much.
Sincerely regards,
