Latest addition, tsched=0 is still required to have decent audio
acquisition, otherwise the audio is stretched in time. A lot. Otherwise,
after setting that, the audio is perfect now.

The only step is to not use tsched and try to use a software that use

As soon as you test your mic, the audio in playback get shifted back in
