Firefox and Chrome are constantly crashing, even with all extensions removed. Everything is updated/upgraded on Ubuntu 20.04. It's been this way for months.

I am running Ubuntu Mate 18.04, recently updated. When I have Spotify playing in my browser (happens either with Firefox or Google Chrome), and I switch to tty1 to work, the music plays 10 or 20 seconds then stops. It automatically starts again when I come back to tty7. It appears the OS decides it doesn't need to run anything graphical while in another tty. The problem also happens with YouTube.

USB DAC: Only youtube has sound on Firefox
cn flag

I have Ubuntu 20.04 LTS and a USB DAC. I'd like to use it play music. So far, I can use Audacious to play mp3/flac with the USB DAC. But with Firefox (91.0 64-bit), it is very strange, only with Youtube, it can play sound. On other sites, including music and video sites, there is no sound at all when playing, although I can see that there is sound output in PulseAudio Volume Control's playback tab.
