Sound not working in Macbook Pro mid 2017

Ask Fedora
,
1

Good evening,

I recently installed fedora spin i3wm on a Macbook pro 2017.
Everything seems to work well except for audio, camera and keyboard backlights.

Not a huge problem for these last two things, but the audio is quite necessary for me .

I’ve tried many things and none of them worked. To be honest I am not such a server audio expert so I don’t actually know what I’ve tried.

This is the result of my inxi -SA:
Audio:
Device-1: Intel Sunrise Point-LP HD Audio driver: snd_hda_intel
Device-2: Broadcom 720p FaceTime HD Camera driver: N/A
Sound Server-1: ALSA v: k5.15.14-200.fc35.x86_64 running: yes
Sound Server-2: PipeWire v: 0.3.43 running: yes

Unluckily no wireplumber.service was found…

I think some installation of pipewire-media-session had removed wireplumber.
I installed it again, but still no luck with the service

Do you see an error when checking ?
systemctl --user status "pipewire.*"

Hi, I just found this doc. If you search ont that page with intel-mac or macbook you’ll get some model available.

You can try by creating modprobe with:

# Create file `mac-sound.conf`
sudo touch /etc/modprobe.d/mac-sound.conf

# Adding configuration
sudo nano /etc/modprobe.d/mac-sound.conf

# Add following line, change <model> with some model available from doc.
options snd_hda_intel model=<model>

# Save with `ctrl + x` then reboot to see if it working or not. If not, you can try with different model.

Some reported by just using options snd_hda_intel model=intel-mac-auto it will select automatically the model for mac audio.

Hi, would you like also to try to install pavucontrol. When we open pavucontrol GUI, on the far right tab there a Configuration tab (please maximize the window) then on part Built-in Audio if there presented with some list of profile, please try to select “Analog Stereo Duplex”.

Also please post the result of aplay -lL (lower case L and upper case L).
