Dear ALSA developers,
I would like to report a regression affecting the microphone on my laptop using Intel's Ice Lake-LP audio controller with the `sof-hda-dsp` driver.
After upgrading `alsa-ucm-conf` to version 1.2.10-150600.3.5.1 (as distributed in openSUSE Leap 15.6), the internal microphone stops working. No capture is possible via `arecord` or any application. The device still shows up in `arecord -l`, but it does not receive audio input.
Rolling back to the previous version (1.2.10-150600.1.2) using: sudo zypper install --oldpackage alsa-ucm-conf-1.2.10-150600.1.2.noarch
restores full microphone functionality.
**System information:** - Distribution: openSUSE Leap 15.6 - Kernel: 6.4.0-150600.23.53-default - Audio device: Intel Corporation Ice Lake-LP Smart Sound Technology Audio Controller (rev 30) - ALSA driver: sof-hda-dsp
**Working `arecord -l` output with the old version:** card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog ( *) [] card 0: sofhdadsp [sof-hda-dsp], device 6: DMIC (*) [] card 0: sofhdadsp [sof-hda-dsp], device 7: DMIC16kHz (*) []
Let me know if I can provide logs, diffs between UCM files, or further testing. I'd be happy to help.
Best regards, Pablo Scatizza Neuquén, Argentina
