There was a problem hiding this comment.
Shouldn't the channel map be mono if it is just one speaker?

Summary
Add the missing
apple-t2x1.confstereo profile.Why
On my Mac mini 2018 (T2) under Ubuntu 25.10, the Apple audio card is exposed as
AppleT2x1.The repo currently ships:
apple-t2x2.confapple-t2x4.confapple-t2x6.confAt the same time, the udev rule already maps the Apple audio device to
apple-t2x%c.conf, so on this machine the audio stack ends up looking forapple-t2x1.conf, which is missing.That leaves the T2 card without the expected profile data for the built-in speaker / headphone-jack layout.
What changed
This PR adds
files/profile-sets/apple-t2x1.conf.The mapping matches the stereo endpoint layout I observed on this Mac mini:
hw:%f,0speakershw:%f,2headphones / codec outputhw:%f,3headset mic / codec inputThe profile itself follows the same structure as
apple-t2x2.conf, using stereo speaker output plus headphone and mic mappings.Validation
Validated locally on a Mac mini 2018 (T2):
AppleT2x1, but the expected profile file was missingapple-t2x1.conf, both built-in speaker and 3.5 mm jack became usable
