@kevineinarsson Nice work! I wonder if it would be possible to enable the woofer for the mbp15,2 too?
The point is, I have no clue about how to properly configure pulseaudio to enable LFE remixing. I tried to add
enable-lfe-remixing = yes
to my /etc/pulse/daemon.conf, however nothing changed. I suspect I need to modify my AppleT2.conf to look more like yours, but my last attempt wasn't a success 😄
Anyone got mic working on MBP 15,2? With this config it appears in pulsemixer but always records silence.
Some recent updates to ALSA seem to have changed where it looks for apple-t2.conf, I resolved that by copying it to the new directory:
sudo cp '/usr/share/pulseaudio/alsa-mixer/profile-sets/apple-t2.conf' '/usr/share/alsa-card-profile/mixer/profile-sets/apple-t2.conf'Here's a reddit post I found about this change
And here's the errors pulseaudio was giving before I moved apple-t2.conf:
E: [pulseaudio] module-alsa-card.c: Failed to find a working profile.
E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="0" name="pci-0000_04_00.3" card_name="alsa_card.pci-0000_04_00.3" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=no card_properties="module-udev-detect.discovered=1""): initialization failed.
E: [pulseaudio] socket-server.c: bind(): Address already in use
E: [pulseaudio] module.c: Failed to load module "module-native-protocol-unix" (argument: ""): initialization failed.
I've used your profile and tweaked it to have it working on my 9,1 (Macbook Air 2020)

Hope this helps someone out there
Doesn’t allow for headphone usage on the Pro16,2

Thank you! Nothing was working for me until I did this. Now works swimmingly on Fedora 35 (even with Pipewire!)
@MCMrARM the updated location for
/usr/share/pulseaudio/alsa-mixer/profile-sets/apple-t2.conf
is now
/usr/share/alsa-card-profile/mixer/profile-sets/apple-t2.conf
as @Redecorating mentioned above. Thank you so much everyone for the excellent profiles otherwise.
If your mic crashes your OS, try adding "intel_iommu=on iommu=pt" to the "GRUB_CMDLINE_LINUX=" line in /etc/default/grub (then "sudo update-grub" for ubuntu, or "grub-mkconfig -o /boot/grub/grub.cfg"). Shoutout to @Redecorating for sharing this fix to us in the discord! I didn't see it documented anywhere else, so figured i'd throw it down as a comment here (since this is the first gist the wiki's audio section links to)
@MCMrARM Do you know what license these files would be under?
Are there any updates that might work with Pop!_OS since it now uses pipewire instead of pulseaudio?

https://wiki.t2linux.org/guides/audio-config/#using-pipewire-instead-of-pulseaudio the change here to 91-pulseaudio-custom.rules should work.

I got the speakers working on a MBP 16,1 by doing some small changes. I also included a sample config to make LFE remixing work so the woofer plays.
