Title:
  Microphone not working after suspend

Status in linux package in Ubuntu:
  Incomplete
Status in pulseaudio package in Ubuntu:
  New

Bug description:
  I have Logitech BRIO 4k Pro webcam connected via its USB cable to Asus
  Vivobook Pro 16X OLED M7600QE-L2014X (90NB0V71-M02190) laptop.

  On Ubuntu 21.10 after suspend (`systemctl suspend`) webcam's
  microphone stops working (device is still there, but audio level is at
  zero all the time).

  To make it work again I need to do 2 things (just one is not sufficient):
  1) Disconnect and connect webcam again to the laptop
  2) Restart pulseaudio with `pulseaudio --kill; pulseaudio --start`

  Not sure whose fault it is, likely kernel driver, but the fact that 
pulseaudio needs to be restarted is concerning as well. Reproducible 100% for 
me.
