@Hui

I did a new round of test.

1. purged alsa-ucm-conf and installed alsa-ucm-conf 1.2.2-1ubuntu0.4.1+test from your ppa

2. tested sound on 4 kernels
   a. mainline generic 5.8.13 and 5.6.19: sound is working fine, Skype echo test included, headset jack plugging and unplugging are managed with no issue
   b. 5.4.48 and 5.6.0 1020 oem: sound becomes garbled/crackling, instability on jack plugging and unplugging, Skype not usable

My conclusion: there's some problematic interaction with the standard kernels.

Does it make sense me to test groovy? It's kernel 5.8
