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.
