No audio/sound at all in snap version

[geekley]

Describe the bug Audio does not play at all on the snap version of codium. It plays normally on the flathub version.

Please confirm that this problem is VSCodium-specific

• This bug doesn't happen in the flathub version of Microsoft's Visual Studio Code either.
• I don't know if it happens in the snap version of MS VSCode (I won't install it) but some issues seem to indicate it happens:
  • https://github.com/microsoft/vscode/issues/179385
  • https://github.com/microsoft/vscode/issues/229786.

Please confirm that the issue/resolution isn't already documented

• [x] I checked the Docs page and the Troubleshooting page and my issue is not mentioned there.

To Reproduce Just open some music file e.g. .mp3, .ogg in the IDE and click play in the widget.

Alternatively, open the developer tools and paste this in the console to play a beep:

const audioContext = new AudioContext();
const oscillator = audioContext.createOscillator();
oscillator.type = 'sine';
oscillator.frequency.value = 440;
oscillator.connect(audioContext.destination);
oscillator.start();
setTimeout(() => { oscillator.stop(); }, 1000);

Expected behavior You get audio normally (music or the beep).

Desktop (please complete the following information):

• OS: Kubuntu 24.04
• Architecture: x64
• Version: 1.96.2
• App Manager: Snap
• Sandboxed: no? Snap was installed with --classic

I thinks it's a permission issue.

Have you tried snap connect codium:audio-playback?

It seems like it would need the following in the snapcraft.yaml:

apps:
  codium:
    plugs:
      - audio-playback

[geekley]

I think I can't even try it without the changes in snapcraft, unless there's another way?

$ sudo snap connect codium:audio-playback
error: snap "codium" has no plug named "audio-playback"

+1, I have the exact same issue. Got the same error of no plug.

[daiyam]

It doesn't work! It won't publish because snap doesn't allow slots/plugs in classic confinement. (https://launchpad.net/bugs/1655369)

Just checked v1.97.1 (snap) and audio is working for me! I tested a .ogg file and the code above in the devtools. I'm curious, how did you solve it @daiyam ? Or did something change upstream? Unless running that snap connect command solved it for me despite the error or something? Can someone else that didn't run this command confirm that audio works now?

[daiyam]

No, I haven't changed anything...

[geekley]

OK, I have no idea what is going on. Sometimes the audio just works, sometimes it just doesn't. I can't understand if there is any pattern, like another app (such as Godot) using audio too or something. Or that web behavior of "you have to click the page first to play audio" (doesn't seem to be the case? or at least in any consistent pattern?)

In any case it doesn't seem to be a snap permission issue. In fact, I'm not even sure anymore that is necessarily snap-specific... that would require extensive testing...
