Bug Description

I have a new Dell XPS 17 laptop and I have a sound issue. Many times some online meeting has either no output sound or no input sound (so I can either not hear or not be heard) because the system shows 2 different input and 2 different output devices, even though I have nothing else connected to the laptop. It is extremely annoying to not reliably start an online meeting for instance; even if I figure it out, changing the input does not seem to work unless I restart Firefox (maybe it does not dynamically detect the sound changes in Settings). I will attach 3 screenshots with the devices but have in mind there is nothing but the USB-C charger connected to the laptop. The Audio Switcher Extension is even stranger, I think it shows all the available USB-C ports (1 is occupied by the charger, 3 remaining) as sound outputs.

A Gnome shell extension shows all available (unocuppied) USB-C ports as output ports for sound.
