No sound in snap when run?

I just installed snap via the archiki instructions.

I installed star ruler 2 from snapcraft and run it with:

Code:snap run starruler2It opens but I get no sound.

There is some error output on the command line related to audio but didn't find a conclusive answer when I looked up the error. Didn't look for long yet though as it was the end of the night and was about done.

Here is the output:

Code:$ snap run starruler2
