The microphone in the Plantronics C320-M headset will randomly fail to initialize properly, at least when using Microsoft Teams. Introducing a 20ms delay on the control messages appears to resolve the issue.

Note: Microsoft Teams is the only application tests have been performed with and no other kinds of investigations have been performed, like USB packet logging. Originally reported as a possible PulseAudio issue, where it was suggested to try a delay quirk in the kernel. If other tests should be performed, please let me know which tests and I will try to do them.
All testing was done on 5.10, patch was then applied on sound.git master for submission
I did not register to the mailing lists, please keep me CC on any comments. Thanks!
Thanks, applied now.
It's a good timing, as I've recently got a bug report for the similar device (C320) showing mysterious behavior on Teams :)
