Topic: Audio dropouts in Babyface Pro & Big Sur
I've been experiencing occasional audio dropouts since the upgrade to Big Sur. They last from 10 secs to a min. Strangely, all the meters on the card and in the Totalmix keep moving, but I can't hear anything, including the signal from the line input. If I stop all audio in the Mac and wait for a while, the dropout disappears but comes back occasionally during the session. Sometimes, even restarting the Mac doesn't work, and I get dropouts very soon after the restart. If I reconnect BF the problem disappears only for a while. I suspect the issue is related to USB drivers. I would appreciate any comment or advise.
Babyface Pro (firmware:v200, driver:3.27, bus powered)
Big Sur 12.4 (iMac intel i5, 16 gb ram)
