Part 19 of 23 of the iPad 5 (J71t) series in this repository; merge after #111.

Problem

The codec's playback mixer source selectors kept whatever value they had, which left a silent or duplicated channel after a codec reset or firmware use.

Change

Assign mixer buses 0 and 1 to ASP RX slots 0 and 1 before enabling playback, as iOS does.

Testing

  • Hardware: iPad 5 Wi-Fi (J71t). Hands-on testing on 2026-11-11 with an integrated build of this series, made before the final failure-path fixes, covered the speakers.
  • Not covered on hardware: headphones. Headphone jack detection is not part of this series: wired headphones are selected by hand with the codec's Output Select control.
  • 2026-11-12: no further hardware test of this change beyond the above. The top of this series applies to the same kernel tree as the release build tested on J71t that day (20+ warm restarts without a freeze).
  • Host: the Linux test suite passes at this branch's head, and the kernel and m1n1 patch series apply on apple-16k and apple-4k. At the top of the series the applied kernel tree is identical to the one in the built release image.
  • Other boards that share these drivers or compatibles have not been tested.

Dependencies

Depends on #111.

This branch is stacked on the PRs it depends on and carries their commits; the change of this PR is its last commit, "ASoC: cs42l81: Initialize the stereo playback mixer sources".

ASoC: cs42l81: Initialize the stereo playback mixer sources
14f0543 
The iPad 5 codec setup programmed the slot layout but left the playback
mixer sources at whatever reset or iOS had left there, which can leave
one speaker silent or both playing the same channel. Route mixer buses
0 and 1 to the two incoming stereo slots, as iOS does.

From orchard PR OrchardLinux#124 (commit bef17c4), unchanged. Only the iPad 5
(J71s/J71t/J72s/J72t) uses this codec.

j71t: Speakers work
0b36f43 
Berkay tested the speakers on J71t on 2026-11-11 with the mixer source
fix (orchard PR OrchardLinux#124). Headphones are not covered: the jack is not
detected, and wired output is selected by hand.

Landing this as your commit, unchanged, with J71t speakers marked working in the device data. The branch now holds only this topic on top of main; your previous head (the whole stack up to here) is kept as tag contrib/brkosebay-j71t-audio. Please check the speakers still play in stereo on the next nightly.

Checked on an iPad 5 (J71t) on 2026-11-13 with a user install image built from main 8ea3182 plus the open 0.4 PRs (top j71t/gpu-handover), installed with orchard install from DFU, then a cold boot from DFU and a warm restart (kexec) from the desktop.

Confirmed: the speakers play in stereo. A left/right test in Firefox played left only, right only, and both, from the correct speakers.
