SDM845 no audio on Linux 6.1.3

January 11, 2023 1 min. read

The Linux 6.1.3 stable upgrade caused a regression breaking audio on SDM845 devices.

The fix can be seen here and the MR to apply it is here

The bug is due to an upstream fix enforcing that all apr sub-nodes in devicetree have the "qcom,protection-domain" property. We have additional apr service nodes for call audio support which were missing this property.

The patch introducing the regression has already been reverted upstream.
