I would be glad to test it on SteamOS, but I do not have a Steam Deck.
Used and tested on desktop with Steam in -steamdeck mode with gamescope

[EMERALD0874]

@allmazz Since this is a new plugin, please recruit a tester in our Discord server or elsewhere who can install and test this plugin on a Steam Deck. That is our primary userbase and any plugins on the store should generally work on Steam Decks unless very clearly intended for other devices.

[EMERALD0874]

Sorry, I misremembered our requirements. It doesn't need to be tested on a Steam Deck, but you do need to test it on SteamOS in general. Please do that and we can move forward with the PR process! :)

Confirming that this works on the Deck

[beebls]

Code LGTM, just want a confirmation that the dependencies you mentioned needing (wpctl and pw-dump) are present on a stock Steam Deck, we don't want plugins that require users disabling read-only or otherwise modifying the system.

If you can confirm that those packages exist on a stock install then I'll get it off to testing.

Yes, they preinstalled since SteamOS uses pipewire with wireplumber and in Arch there is no separate package pipewire-tools like on Fedora. Kindly confirmed and tested by a discord server member.

Plugin Testing Report

Plugin: decky-volume-mixer / Mixer
PR: #1019
Tester: BRiAn3274
Device: Steam Deck OLED 512GB
SteamOS channel: Stable
SteamOS version: 3.8.11
Steam version: 1782533657
Decky Loader version: v3.2.6
Install method: Manually installed from PR build for testing

Test Environment

• Steam Deck: Steam Deck OLED 512GB
• Mode: Game Mode
• SteamOS version: 3.8.11
• Steam version: 1782533657
• Decky Loader: v3.2.6
• Installed plugins during this test:
  • AirDeck
  • Mixer
  • Decky Clash
  • KDEck

Summary

I tested Mixer on a real Steam Deck OLED in Game Mode. The plugin installed and appeared in the Decky quick access menu, but it failed to load when opened.

The plugin showed a SteamUI / Decky plugin loading error immediately, so I was not able to test the volume mixing functionality.

Installation

• Installed Mixer from the PR build.
• The plugin appeared in the Decky quick access menu.
• Opening the plugin resulted in a load error.
• No further functional testing could be completed because the frontend failed to load.

Error Observed

When opening Mixer, Decky displayed the following error:

SyntaxError: Unexpected token 'export'
at PluginLoader.importReactPlugin
at async PluginLoader.importPlugin
at async Promise.all
at async PluginLoader.loadPlugins

[BRiAn3274]

I am also submitting my own plugin, KDEck, here:
#1067
If you have time, I would appreciate a test report in return. KDEck focuses on KDE Connect-style clipboard and file transfer in Game Mode.

Are you using latest loader? I tried to reproduce it on latest stable SteamOS with plugin version from the store, but plugin loaded successfully. Or, could you try to unload other plugins temporary please? Error looks really uncommon, I think it's about installing/packaging/loader side error, not plugin itself.

I updated the client/loader and the issue disappeared on my side. It may have just been a coincidence, or something specific to my Steam Deck setup.

Sorry if this caused any confusion. I think this can be ignored for now unless it happens to someone else too.
