Big Sur 11.3 and 11.3.1 Audio issue Safari Youtube with external sound card MOTU M4

Hi guys,

Since 11.3 my external sound card - MOTU M4 and Safari QuickTime playbacks are not going well.

Every now and then youtube playback videos start cuts every 10ms or so.
Here is how it sounds

Every other player - Spotify/Firefox/VLC/TIDAL works fine in parallel.
Audio MIDI Interface is stock settings.

​

So far I found that

• restarting the Audio Interface fixes it for some time
• restarting Core Audio "sudo killall -9 coreaudiod" works for a bit

Anyone faced such issue?
