Thanks for the link !
This version, although far from perfect, seems better ! The interuptions have been reduced just enough so it does not disrupt MP3 playing in Media Player. Will have to test with my recording software ( Reaper ) but I find the level of interuption quite high and unsafe for audio recording.
Hopefully, this version being only Beta, the final version will be even better. The developpers are on the right track this time. Aim for <1000µs !
Here are my results both taken just before and after the install of the new driver:
