@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.

Thank you! Nothing was working for me until I did this. Now works swimmingly on Fedora 35 (even with Pipewire!)
