Compatibility Report

  • Name of the game with compatibility issues: Void Crew
  • Steam AppID of the game: 1063420

System Information

steam-1063420.log

I confirm:

  • [x] that I haven't found an existing compatibility report for this game.
  • [x] that I have checked whether there are updates for my system available.

Symptoms

I can create and join online multiplayer games, but other people cannot hear my microphone input. KDE Plasma's volume mixer shows the game's output audio streams, but no input audio stream seem to be created for the game. Steam's own voice chat works fine, as does Discord. From what I've found out, the game uses Unity3D as game engine, Fmod as audio engine, and something called ViVox for multiplayer audio communication. Presumably the latter two come bundled with Unity3D.

Reproduction

  1. Start Void Crew
  2. Click on HOST GAME
  3. Click on PLAY
  4. Press Esc
  5. Click on MICROPHONE MUTED so it toggles to UNMUTED
  6. Try to speak into a connected microphone and see whether the icon to the left of player name/unmuted status lights up or not. For other connected players it lights up, but for me it does not
  7. Click on SETTINGS
  8. Click on AUDIO
  9. Try to change AUDIO INPUT DEVICE from PulseAudio Input to Scarlett 8i6 USB Multichannel, or whatever audio card/chip your system has
  10. Click on APPLY SETTINGS
  11. Press Esc
  12. Repeat steps 6-11 as necessary for testing

I have good news. I have found a workaround, and possibly also some information that can help fix the issue.
So, whenever I start the game with the microphone for my Bluetooth headset selected as default in the KDE Plasma sound settings, the audio recording stream for Void Crew gets created, so I can just change the default after launching the game to get mic input working.

So for whatever reason, when either Void Crew or Proton, I'm not sure which, looks for input devices it doesn't find the one set as default in Plasma sound settings. But setting another input device as default after launching the game works around the issue. It's still a bug, since just launching the game with previously working settings should be enough to have it work as before, but that's not happening and thus changing the default microphone after launching the game is a workaround for now.

Reproduction Steps

Launch Void Crew.
Host or join a multiplayer game.
Press Esc, click "Microphone Muted" to toggle it.
Speak into your mic — icon does not light up.
Go to Settings > Audio.
Try changing Audio Input Device.
Apply and retest.

No mic input is recognized despite changes.

Workaround Found

Set a different input device as default in KDE Plasma sound settings before launching the game, such as a Bluetooth headset mic. Then, switch back to the preferred input device after launching.

This forces Void Crew (or Proton) to detect and create the audio input stream. Once it's created, switching devices works as expected.

Likely Cause

The game (or Proton) fails to detect the default microphone device during startup.

No fallback detection or runtime refresh of input devices after launch.

Suggests initial input device enumeration bug, likely related to how Unity/FMOD/ViVox interfaces with PulseAudio or PipeWire via Proton.

Root Cause not identified, but likely Proton/Unity audio input enumeration bug.
