Cannot parse dump frequency: "sysfs", Unknown PCM default

Hello, I am trying to prepare a new version of our game, deerportal, and in the latest snap something strange is happening. I have plugs - pulseaudio etc. I am pretty new in snaps, any advice/help will be appreciated. Snapcraft file: https://github.com/deerportal/deerportal/blob/master/snapcraft.yaml

There’s two issues here:

  1. Your application seems to be attempting to use alsa, not pulseaudio.
  2. Your application is trying to load the sound files from a location outside of the snap (/share/games/deerportal/assets/audio/dice.ogg). You need to coerce it to look for the files rooted with $SNAP; some applications provide environment variable overrides for such redirections.

Hi, thank you for the answer.

As far I understand issue with non accessible file, I don’t know what I should do with ALSA thing. When I compile game out of snap it seems to be using pulseaudio.
