Thanks for the explanations. I'll keep working with pulseaudio+ucm for
now so as to be able to test your fixes. If it becomes too unbearable
I'll revert to dmic_detect=0
>About the issue on google meet, it is a problem, do you also meet the
similar issue on other audio apps?
Regarding the microphone issue, it seems to be chromium specific,
possibly related to the fact that chromium is a snap and is therefore
sandboxed.
here is the corresponding dmesg trace :
