Hi,
A user reported that our app, antstream-arcade, has no sound in Linux Mint 20, which I could verify as correct after installing that distro and our snap package.
When running the app for the first time, this dialog appears:
After closing the app, issuing sudo snap connect antstream-arcade:alsa
in a terminal, and opening it again, the dialog is gone, but still no sound. In the terminal I can see the following messages:
$ antstream-arcade
Testing for explicit PulseAudio choice...
Testing for ALSA permissions...
...and using ALSA.
