Same PX13, kernel 7.3.3, with two modules swapped: - snd-soc-tas2783-sdw: unmodified v7.4-rc1 tas2783-sdw.c/tas2783.h - snd-soc-sdca: v7.3.3 plus only the sdca_functions.c fallback from SOF PR #5904 (function type for mfg 0x0102 / part 0x0000) Kernel log: acpi device:26: function type not a DisCo constant, using fallback for known peripheral acpi device:26: SDCA function SmartAmp (type 1) at 0x1 acpi device:28: function type not a DisCo constant, using fallback for known peripheral acpi device:28: SDCA function SmartAmp (type 1) at 0x1 slave-tas2783 sdw:0:1:0102:0000:01:8: Found Smart Amp function at index 0 slave-tas2783 sdw:0:1:0102:0000:01:b: Found Smart Amp function at index 0 speaker-test -c2 -t wav: Front Left from the left speaker, Front Right from the right speaker. No "Defer on undeferrable control" warnings (with the same fallback on the v7.3-rc6 driver I saw ~1600 of them during playback). So on the PX13 the v7.4 driver works as intended once the ASUS SDCA function is parsed. The regression is only that the parse fails on this firmware. Getting the PR #5904 fallback (or an equivalent) into v7.4 would fix it without bringing back the split. I can test a posted version. https://github.com/thesofproject/linux/pull/5904 Thanks, Lee Mann
