Audio dropout problems with MacBook Pro (14-inch, 2021), Behringer UMC204HD USB audio interface

Thanks Melissa. I tried a different user account and no audio problems with that. Though I think that was due to low memory usage in that account rather than account specific issues.

After more investigation the problem seems to occur only when Memory Pressure (in Activity Monitor) is yellow, especially when I have Windows 11 running in a VM , which uses a lot of memory and takes Memory Pressure from green to yellow.

Though with my old Late 2013 MacBook Pro I ran it with Memory Pressure in the yellow zone all the time and never had a problem with audio dropouts.

Both systems have 16GB of RAM, which is generally enough for my normal usage other than running the VM.

I am running an external LG monitor connected via USB-C with my new system. Though I tried without any external monitor and the dropouts still occur when Memory Pressure is yellow.

That's not very helpful. This is an M1 MacBook Pro, so there is no way to increase memory. As I said previously, this problem NEVER occurred with my old Late 2013 MacBook Pro when I ran it with Memory Pressure in the yellow zone all the time, and with the same amount of memory as I have in my new MacBook (16GB). So seems to me this is an Apple problem or perhaps a USB-C to USB2 conversion problem.
