Title:
Audio output & input routes to usb-c hub (where audio jack is
disconnected) instead of laptop speakers
Status in pulseaudio package in Ubuntu:
Opinion
Bug description:
I'm using Ubuntu 21.04 with an intel tablet and a lenovo usb-c hub
that has an audio adapter: See https://linux-
hardware.org/?probe=09f8c72d80/
I never have anything hooked into the audio jack on usb-c hub, yet
every time I plug my tablet into the usb-c hub the sound output
switches to the usb-c hub instead of staying routed to the tablet
speakers. I then have to go either into settings or use a sound output
extension to switch it back to the speakers.
This issue does not happen when using Windows 10 - audio stays routed
through the tablet speakers - my guess is that it goes a step further
and detects whether an audio jack actually has a cable plugged in or
not.
What package handles determining default audio routing for Ubuntu
21.04 / Gnome 3.38.5? I'd like to file a bug about this / possibly see
if I can help make the defaults work better.
