Set app audio device not working on Windows 11

[GeekyEggo]

Description

• The devices list does not load for the "Set app audio device" action on Windows 11.
• The "Set app audio device" fails with a warning icon on Windows 11.

Cause

There were interoperability changes to Windows 11 that are resulting in Sound Deck being unable to instantiate the IAudioPolicyConfigFactory. This factory is required to enable the changing the audio device of an application.

Reading

The only other known application to provide pragmatic switching of audio devices for applications is EarTrumpet, however initial tests have been unsuccessful within Sound Deck.

Quick update; this evening I updated to the Windows Insider program to get access to Windows 11. I've located the bug, and will be working on a fix tomorrow.

For what it's worth, I checked this out, built it (minus the UI) and it's working again for me 👍

Thanks! 💯

[GeekyEggo]

That's great news, appreciate you testing it, @rikward. Once I've tested it's still working on Windows 10, I'll release a new version on the official store.

You know when the update is ready? @GeekyEggo

[GeekyEggo]

@Loco360 I haven't had a chance to test Windows 10 yet sadly; you can however download the beta version directly. This will include the fix for Windows 11. (download link)

Merged to main.

I'm having this issue with latest Windows 11 and
Stream Deck version: 5.1.3.14750
Sound deck version: 3.0.2

When I press the button to change the forground app audio device the only thing that happens is that there is a triangle with a exclamation mark that appears on the stream deck button.
Is this normal?

[GeekyEggo]

@ManaHime that's odd, let's see if we can determine what might be causing the problem.

1. Is this a new action, or a previous action?
2. Is the "Audio Device" correct in the action settings? (Windows 11 is frequently resetting device IDs, so you may need to re-select it).
3. What application are you trying to set the device for?

[ManaHime]

1: I tried creating a new action because the previous actions did not work.
2: I have noticed this so I usually make sure to look at the audio devices when I restart my computers (otherwize they'll default to something I don't want to use, like the wireless adaptor for my wireless headphones)
3: I've tried both Chrome, Discord and Parsec.

So I just
1 create a new action
2 then set the audio device I want to use
3 alt tab to the app
4 press the button
5 only a triangle appear with no change in audio device

If you're happy to, would you mind uploading your log files; they can be found here: %APPDATA%\Elgato\StreamDeck\Plugins\com.geekyeggo.sounddeck.sdPlugin\logs

[ManaHime]

Thank you so much for your help.
It turns out that somehow now this is working correctly with Parsec and Discord (go figure... I blame murphy's law); however, Chrome is still messing up for some reason.

Thanks @ManaHime; this might be related to applications that use multiple processes. Nothing jumps out in the logs, but I'm going to add a bit more information so that should it happen again in the future we'll know more.

[ManaHime]

@GeekyEggo Thank you so much for the help!
Not having the ability to change the device for Chrome (and Edge... though I don't use Edge) is a little troublesome, but the really important thing for me really was Parsec, and since that works I really don't mind about anything else ＾＾

I'll post again if I find more information ＾＾

Thank you very much!

@ManaHime out of curiosity, does Chrome work if you configure the action to use "By Name", with "chrome" as the name value.

[arimorcos]

@GeekyEggo I'm also having this issue, trying to switch chrome between default output and headphone chat output. Here's an image of my two configs:

When I click the buttons, it shows a checkmark, but looking in volume mixer, the audio output does not change. I've also tried with "chrome.exe"

Thanks!

[GeekyEggo]

@arimorcos, your configuration looks correct. Having recently helped a friend with audio problems relating to the Wave Link, I wonder if the problem might relate to the wireless headphones. This is purely speculation, but in her case she had two devices listed for the same wireless device; one was named "Headphones", and the other "Headset". Are there two listed for you also?

[arimorcos]

@GeekyEggo, thanks for the quick reply!

There are multiple headphone devices, but they all refer to different audio outputs. See photo here:

I've checked for logs, but there's no log file in %appdata%\AppData\Roaming\Elgato\StreamDeck\Plugins\com.geekyeggo.sounddeck.sdPlugin

[GeekyEggo]

Oh wow, that's a lot of virtual devices for a headset. 😅 Out of curiosity, does it work if you attempt to change between two wired devices, e.g. the LG monitor, and "Realtek Digital Output"?

Logs should be available at %appdata%\Elgato\StreamDeck\Plugins\com.geekyeggo.sounddeck.sdPlugin\logs.

[arimorcos]

Haha, ya most of them I never use. I actually just disabled most of the them but it still doesn't seem to work. Also doesn't for any of the other audio devices.

There was one thing in the log just now:

2022-09-02 15:47:52.2237 [ERROR] SoundDeck.Plugin.Actions.SetAppAudioDevice: Failed to set app audio device; AudioDeviceId="{0.0.0.00000000}.{4082c9ca-dbaf-427a-b0ff-52c755e23866}", ProcessSelectionType="ByName", ProcessName="chrome.exe".
System.Collections.Generic.KeyNotFoundException: Unable to find audio device with key {0.0.0.00000000}.{4082c9ca-dbaf-427a-b0ff-52c755e23866}.

   at SoundDeck.Plugin.Actions.SetAppAudioDevice.<OnKeyDown>d__4.MoveNext() in C:\git\SoundDeck\Src\SoundDeck.Plugin\Actions\SetAppAudioDevice.cs:line 45

However, I've pressed the button and gotten a check a bunch since 15:47, and it only seemed to log an error that once even though it didn't change the output device of chrome. It also doesn't seem to work for other apps or foreground process.

[GeekyEggo]

Apologies for my late response @arimorcos; I find it particularly odd that it works sometimes, and not others, ha 😅. Since your post, have you had much luck with the action?
