The cirrus logic audio codec does not support the macbook pro 2016 soundcard, yet.

Hi I tried to patch patch_cirrus.c but didn't help. May be this failure stops the audio driver to do its work. May 05 23:56:49 localhost kernel: snd_hda_intel 0000:00:1f.3: failed to add i915 component master (-19)

Created attachment 256239 [details] new alsa-info.txt with 4.11.0 and applied patch to output looks different.

The codec chip is unknown, so the driver applied the generic method, thus passing model option doesn't work at all since the model option is specific to the codec drivers. For most of Macs, the required quirks are to reprogram the default pin configurations and to turn on the GPIO pins. You can do both of them dynamically and via "patch" firmware. Let's begin with GPIO. You can turn each GPIO pin on/off like: hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x01 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x01 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01 This is for the first GPIO (bit 0). For GPIO2, use bit 1, i.e. replace 0x01 with 0x02. For GPIO3, replace it with 0x04. And so on. You have up to 8 GPIO pins. Some of them might control the amplifier for the headphone and the speaker, according to the past experience with Apple devices. Also, you should check the detectable pins, e.g. use hdajackretask. BIOS often give the incorrect default pin configuration, and you may have to reprogram by yourself. Once when you figure out the setup, it can be put in "patch" firmware file. See Documentation/sound/hd-audio/notes.rst "Early Patching" section. The remaining issue, the i915 error, is strange, though. It means that you have no Intel graphics on your machine, or i915 driver isn't used, or i915 driver isn't loaded properly before HD-audio. But this error shouldn't affect to the analog I/O.
(In reply to Joël Krähemann from comment #5) > alsamixer shows only one control for PCM. It's because you're running PulseAudio and alsa-lib pulse plugin. Run alsamixer with -c0 option.
No I don't have any pulseaudio. I do linuxfromscratch.org

Created attachment 258253 [details] patch to patch_cirrus.c some init verbs found in the net it is of a windows driver's .inf file.
Is audio working now with this patch?
no not at all. Today, I test some additional verbs of the 420x driver. I think it is used by the emulated 8409 driver, too.
I have tried to check GPIO pins using this little script: `hda-verb-on.sh:` ``` hda-verb /dev/snd/hwC0D0 $1 SET_GPIO_MASK 0x01 hda-verb /dev/snd/hwC0D0 $1 SET_GPIO_DIR 0x01 hda-verb /dev/snd/hwC0D0 $1 SET_GPIO_DATA 0x01 ``` with arguments: 0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80 without any success. The last argument 0x80 resulted in 0xffff... value, all others resulted in 0x00 value. I did not hear anything neither from `speaker-test` nor from my browser youtube video. I have also tried to run `rmmod snd_hda_intel && insmod snd_hda_intel` before every script run to reset all pin settings (without success). Questions: - Did I test the GPIOs correctly ? - What can I try with the `hdajackretask` ? Should I just try random pin assignments and hope for the best?
Hi, I think the HDA codec contains an integrated circuit: MAX98357BEWL
I see some discussions on patches alsa-devel [0] where this bug was referenced, are these patches for the same bug? What's the status of this bug / effort? [0] https://www.spinics.net/lists/alsa-devel/msg71179.html
Over on https://bugzilla.kernel.org/show_bug.cgi?id=110561 some info was posted regarding these MBP's. To summarize what has been there and elsewhere, it seems we have the following chips in play: MBP13,1: Cirrus Logic CS8409 (HDA Codec) Cirrus Logic CS42L63A (Mic+HP ADC/DAC) Analog Devices SSM3515 (Speaker Amps) MBP13,2, MBP13,3: Cirrus Logic CS8409 (HDA Codec) Cirrus Logic CS42L83A (Mic+HP ADC/DAC) Maxim MAX98706 (Speaker Amps) In terms of datasheets for these: CS8409 - not available, and no good similar has been found either CS42L63A/CS42L83A - not available, but CS42L42A appears to be more or less identical; datasheet at https://statics.cirrus.com/pubs/proDatasheet/CS42L42_F4.pdf SSM3515 - datasheet at https://www.analog.com/media/en/technical-documentation/data-sheets/SSM3515.pdf MAX98706 - not available, but MAX98372 appears to be more or less identical; datasheet at https://datasheets.maximintegrated.com/en/ds/MAX98372.pdf The various chips are connected via an I²C bus, with the CS8409 acting as the master; GPIO pins 6 and 7 on the CS8409 are SCL and SDA, respectively. The slaves have the following addresses (in hex): CS42L42: 90 SSM3515: 28, 2a, 2c, 2e MAX98706: 62, 74, 72, 74 As to interpreting the *I2C command strings David Ulrich found in the Windows 10 registry (see bug 110561 for details), they appear to follow the following format: <num-devices>[<slave-address>...]<num-reg-writes>[<register><value>...] This is to be run as foreach slave-address do foreach reg-write send I²C command sequence: S slave-address-write register value E For example, "ExitI2C"=hex:04,28,2a,2c,2e,01,00,83 should be executed as the following commands: S 28 00 83 E S 2a 00 83 E S 2c 00 83 E S 2d 00 83 E (writing 83 to register 0 on the SSM3515 powers down and resets the device) From this we can also see that the "InitI2C", "n0AStreamStartI2C", and "n0AStreamStopI2C" command strings only target the CS42L42, not the amps. Lastly, the format of the "ExitVerbs" registry entry is as follows: each 4-byte block is a little-endian HDA command verb representation of an HDA verb. For reference (from section 3.7 of the HDA spec): a 32-bit command verb has the format [codec-address(4)][node-id(8)][hda-verb-param(20)], and an hda-verb-param is either 4+16 bits or 12+8 bits. So the above ExitVerbs are: codec nid verb param (linux verb constant) 0 01 705 00 (AC_VERB_SET_POWER_STATE) 0 47 5 0001 (AC_VERB_SET_COEF_INDEX) 0 47 4 0000 (AC_VERB_SET_PROC_COEF) 0 47 5 0082 (AC_VERB_SET_COEF_INDEX) 0 47 4 0000 (AC_VERB_SET_PROC_COEF) 0 47 5 0003 (AC_VERB_SET_COEF_INDEX) 0 47 4 8000 (AC_VERB_SET_PROC_COEF) 0 47 5 0004 (AC_VERB_SET_COEF_INDEX) 0 47 4 2801 (AC_VERB_SET_PROC_COEF) 0 47 5 0006 (AC_VERB_SET_COEF_INDEX) 0 47 4 8000 (AC_VERB_SET_PROC_COEF) 0 47 5 0007 (AC_VERB_SET_COEF_INDEX) 0 47 4 2801 (AC_VERB_SET_PROC_COEF) 0 47 5 0065 (AC_VERB_SET_COEF_INDEX) 0 47 4 0000 (AC_VERB_SET_PROC_COEF) 0 47 703 00 (AC_VERB_SET_PROC_STATE) 0 01 705 03 (AC_VERB_SET_POWER_STATE)
I have been able to get audio on my MacBookPro 14,3 essentially replaying a log of the HDA commands sent under OSX. The 14,3 from what I can see is the same chips as 13,2 and 13,3. Cirrus Logic CS8409 (HDA Codec) Cirrus Logic CS42L83A (Mic+HP ADC/DAC) Maxim MAX98706 (Speaker Amps) All setup is done by writing to undocumented coef indexes of the vendor node 0x47. None of the usual HDA tricks are going to work. The I2C setup is also coded using writing/reading to coef indexes of the vendor node. The highly experimental patches are in https://github.com/davidjo/snd_hda_macbookpro. This is not meant as a working audio system for Linux. It does play 24 bit (S24_LE), 44.1 kHz 2 or 4 channel audio (this is format programmed by OSX). There is no volume control. Curiously I see very little overlap between what OSX sends and the Windows strings in the cs4208_38.inf file (needed for the 14,3 model) from Bootcamp driver.
On MacBookPro13,3 I can confirm this patch is working as well with built-in audio.
The built-in input/output audio is working for MBP models 13,3 and 14,3 for kernel version 5.5.0+ with the Cirrus 8409 HDA chip driver patch from https://github.com/davidjo/snd_hda_macbookpro, maybe this patch can go into the upstream some time soon if it's stable enough?

Hi We appreciate all the work done for Mac-Pro audio driver. As noted in : https://github.com/davidjo/snd_hda_macbookpro/issues/122 This work needs to be included in the base kernel and get out of this out of tree driver activity . You are at risk of producing another abandoned , orphaned driver eventually. It happens all the time.
