MacBook Pro 2015 13-inch bug with android app sound

[ghost]

I used version 87 with Rammus image. Almost everything works including backlit keyboard but sound is not working once I launch and do something on Android application. For example, If I launch Google Play Store in middle of listening to music, the music will continue to play but without sound as if it's muted.

So basically, I can't hear any sound from Android apps, such as Android games.

Is it to do something with Sound Card driver or it is just a bug with Rammus image? I'm planning on trying version 86 with Eve image, though.

__Update: Tried version 86 from Eve. The issue persists. I think its driver built into Brunch is causing this issue.

Could you update to the latest release in the brunch-unstable repo ? Not sure if it is related but I fixed a sound issue that was present in the latest stable.

I tried unstable repo one, but sound issue persists. To recreate this issue, boot to live usb at least twice (Which will only show "Brunch Framework is loading" instead of creating / applying rootfs), then sound breaks whenever I try to run any android application.

Newest version of Brunch on MacBook Pro 2015 13-inch. The issue persists but I caught more detail.

I guess OS "thinks" headphone is plugged in when android app is launched (and do at least one click within android app). Before running android application, MacBook's headphone jack glows in red, when at least one click is done within android app, the light on headphone jack shuts off and audio comes back after putting headphone into headphone jack then removing it again. (Weirdly, headphone jack does not glow right after pulling out headphones but once I play any sound it starts to glow again.

In addition, with using HDMI output as audio output, it does not happen.

I think this issue is typical on Linux for Mac devices, such as https://askubuntu.com/questions/643757/red-light-from-headphone-jack-macbook-pro-running-ubuntu-14-04, https://askubuntu.com/questions/777640/help-me-kill-this-red-light-coming-from-headphone-jack. It looks like the root cause of this is audio driver.

I am wondering if it could be related to the SPDIF issue in the below thread: https://bbs.archlinux.org/viewtopic.php?pid=1492432#p1492432

Could you try to mute IEC958 as suggested in the edit part of the comment 11 ?

[sebanc]

Otherwise, there is also a specific snd-hda-intel model for the macbook pro 2015. Could you try to add "snd_hda_intel.model=mbp81" on the kernel command line (in the grub configuration, after cros_debug) ?

I creted script and executed it, but it does not fix it. Sound issue with Android application still persists. However, one thing is at first time boot (With initial setup and stuff), it works fine, but after setting up all and reboot, then every problem mentioned occur.

I also tried this, but makes no difference.

[sebanc]

Could you attach the output of "lsmod" in crosh shell to this issue ?

[ghost]

In addition, it happens from the first boot now. It is really weird that it is occurring.

[sebanc]

Could you try to add "modprobe snd_hda_codec_cirrus" in /etc/init/preui-probe.conf (under "modprobe i915") ?

[sebanc]

Also, could you try kernel 4.19 and 5.10 ? (replace /kernel in the grub config respectively by /kernel-4.19 or /kernel-5.10)

[ghost]

Neither of options make sound on android apps work.

[sebanc]

Sorry but I am out of ideas for now, maybe try to switch sound related chrome flags.

[sebanc]

I thought of something, maybe you can try "options=internal_mic_fix" (even though it is not its main purpose, it fixes the sound card order which might be related to your issue)

[Pinoguino]

I have the same problem with the same macbook pro 2015 13 inch. I tried the options=internal_mic_fix but it doesn't fix the problem

[sebanc]

I am not sure if macbooks are supported by the new SOF kernel sound driver but it seems to be functional in latest brunch-unstable releases.

If someone following this issue is interested to try it, you can try using the latest "brunch-unstable" release and adding "snd_hda_intel.dmic_detect=1 module_blacklist=snd_hda_intel,snd_soc_skl" to the kernel command line.

[Pinoguino]

I'm interested how i can try the latest brunch unstable ?

[sebanc]

The brunch-unstable releases are here: https://github.com/sebanc/brunch-unstable/releases

[Pinoguino]

Thanks but with this brunch i created a new chrome.img but i face a bootloop

[sebanc]

Could you try another clean install ? I was actually going to release this build as stable, I would like to be sure there is an issue with it.

[Pinoguino]

Unfortunately i am trying to do a clean install. But when i boot in normal, the loading brunch image appears and then i have a black screen then a bootloop. When i go in debug mode i can the loading process but i have a bootloop too

[sebanc]

Could you attach a short video of the boot process in debug mode ?

[Pinoguino]

[sebanc]

Unfortunately, I cannot really see the log lines on the video. Did you see the brunch rebuilding rootfs boot images on first boot ?

[Pinoguino]

Yes

[sebanc]

If you could a video close to the screen it would help debugging this. Else you can also try 5.10 kernel (replace "/kernel" by "/kernel-5.10" in the grub config.

[Pinoguino]

I think it was blurry because it was in 360p you can retry and play the video in 1080p (the option is present now), i will do an another video

[Pinoguino]

[sebanc]

Thanks for the new video. It confirms that something went wrong with the install, could you re-download the recovery image and brunch andr try again ?

[Pinoguino]

It finally work (for the new image), i have add the kernel command lines and rebooted. After that i can't turn up the volume

[sebanc]

If I understand correctly, sound does not work with "snd_hda_intel.dmic_detect=1 module_blacklist=snd_hda_intel,snd_soc_skl" added on the kernel command line, right ? Is the android apps sound issue still present without those kernel command line parameters ?

[Pinoguino]

Yes the sound does not work with the kernel line. And the the android apps sound issue is still present without those kernel line

[Pinoguino]

I have the latest brunch unstable and today r89 was released. I updated my laptop and after the reboot the sound is working again in android app. I reboot my laptop multiple times to see but i don't know why now it's working
