Cannot repro in a fresh VM. It launches to the login screen at least. What happens if you try with a fresh user account...or backup and delete the config?

Removing the config completely yields the same result; removing the cached login credentials indeed gets me to the login screen but once I'm logged in it gives the same error.

The backtrace from `.cache/ncspot` is the following:

I attach the log obtained using the `--debug` flag.

It has clearly got something to do with the audio backend defaulting to Rodio for some reason; perhaps we shouldn't compile with `--all-features` as the alternative audio backends (PortAudio, Rodio) are intended for use with Windows/MacOS/BSD (see https://github.com/hrkfdn/ncspot/#audio-backends).

Perhaps it would be best to compile without portaudio and rodio dependencies, as Linux users shouldn't need them. It seems to me like a superflous dependency

Could you try ncspot 0.12.0-5? Let me know how it goes.

It works as intended now, thanks!
