Hi,
Since 7.2.11 the sound card is missing on a Dell XPS 14 DA14260 (Panther
Lake, subsystem 1028:0db9, CS35L57 amps on SoundWire):
sof_sdw sof_sdw: ASoC: CODEC DAI cs35l56-ot25 not registered
Fedora 7.2.9-200.fc44 works. 7.2.11-200.fc44 is broken. I did not test
7.2.10.
7.2.11 has bf7a3ce1d563 ("ASoC: sdw_utils: Switch CS35L56/57/62/63 to use
OT25 DAI"), but not the upstream commit before it, 86c8360c97f6
("ASoC: cs35l56: Add DAI for SDCA OT25 stream"), which adds that DAI.
I looked into this with help from Claude Opus 5.5 and checked it
myself. I understand you must get lots of AI generated emails
nowadays; I hope this is helpful nonetheless.
#regzbot introduced: bf7a3ce1d563
Thanks,
Connor

Should now be fixed in 7.2.12, right?
