No sound in snap when run?

snapcraft

I just installed snap via the archiki instructions.

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

snap run starruler2

It 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:

Hi ! @snapcraftuser10903.

Can you show the content of your *.yaml file ?

Where is the path for that please? I am new to using snap and a quick search did not retrieve an immediate answer where it may be located.

@snapcraftuser10903 are you the owner of this snap starruler2 ? :face_with_monocle:

@snapcraftuser10903, It is unclear from the log above whether the problem is with this snap, or with the host environment. Some things that may help are:

  1. checking the plugs connected for the snap snap connections starruler2
  2. the output from snap --version

In particular, is the `audio-playback" plug connected?

You can format the output better by surrounding the text with triple backtick “`” markers.

@baldeuniversel, it looks like the snap owner is @lucyllewy

In passing, I note that the snap hasn’t seen any updates for some years, which implies it isn’t being actively maintained.

EDIT: scratch that! Audio is working now! I remembered I didn’t have pulseaudio installed before and did not want to reset last night to test the changes. I just ran it now and on start didn’t see the audio warnings mentioned in OP and had sound!

I have another question…

How do I install mods on a snap?

Also…

I tried the snap because building the game from source from the git repository didn’t work. In this case it caused black screen of death and would hang and I would have to restart the machine. Any guesses why the snap would work when the git install wouldn’t?

I will note I installed on another machine from the git some years ago and had no issues, just this latest machine I use.
