alsa-project/alsa-ucm-conf pull request #814 was opened from dangowrt:
Add a UCM profile for the SOF variant of the MediaTek MT8186 (Kompanio 520)
sound card `sof-mt8186_rt1019_rt5682s`, as found on Corsola-family Chromebooks
(e.g. google,steelix).
The card exposes:
- RT1019 amplifier -> speaker (SOF_DL2 -> I2S3)
- RT5682S codec -> headset jack: headphones (SOF_DL1 -> I2S1) and headset mic
(SOF_UL2 -> I2S0)
- MT6366 built-in digital microphone (SOF_UL1)
RT5682S DAC/ADC routing follows the existing mt8195 mt6359-rt1019-rt5682
profile (same codec), with board specifics:
- MT6366 internal DMIC needs one-wire mode (`Mt6366 Dmic Mode Switch`)
- headset-mic capture (SOF_UL2 -> I2S0) needs the AFE
`UL2_CH1/CH2 I2S0_CH1/CH2 Switch` interconnect
- a moderate analog capture gain for the headset mic
Tested on google,steelix (Debian, PipeWire): speaker, headphones, headset mic
and built-in mic all validated end-to-end; jack detection works.
`alsa-info.sh` output (per CONTRIBUTING, for the UCM validator):
Note: this card is not yet in the `alsa-tests` validator set, so the CI may
not fully emulate it until the alsa-info above is added there.

`alsa-info.sh` output (per CONTRIBUTING, for the UCM validator) to follow — I
will attach it so the card can be added to the `alsa-tests` validator set. CI
may not fully emulate this new card until then.
