Host: MacOS 10.14.6 on 2018 MacBook Pro Parallels: 14.1.3 Guest: Windows 10 Pro (x86) (1903, I believe). Parallels extensions installed. Problem: As soon as the guest OS tries to play a sound, the guest OS locks up (no mouse or keyboard activity is recognized) and the little blue light under the speaker in the upper-right of the guest OS window (showing audio activity) flashes about 3-4 times per second. "Soft" events (like "Shutdown", "Restart", "Suspend") do nothing; I have to use "Stop" or "Reset" Muting the audio in the guest OS prevents it from hanging. Ideas?
