Switching between playback devices with hotkey doesn't work in specific app (Playnite) when Quick Menu is disabled

[Super1337Boy]

Describe the bug I use an application called Playnite to launch games on mye computer, and when Playnite Fullscreen is running and in focus I have a strange issue with SoundSwitch where switching playback device with the hotkey just mutes the audio from Playnite. The only way to get audio back is to restart the application.

Even weirder is it that this only happens when the Quick Menu is disabled. If I enable the Quick Menu, switching devices with the hotkey works just fine. (But I would prefer to disable it since it takes focus away from the running application until the Quick Menu has faded away.)

Since switching works as expected on the desktop and in games even with the Quick Menu disabled this is probably related to how Playnite handles audio, but the difference in behavior between having the Quick Menu enabled and disabled makes me think there is a problem with SoundSwitch as well.

Is there some kind of difference between how switching is done with and without the Quick Menu that could be causing this? If so, could this be changed?

Version SoundSwitch v6.4.2.0

To Reproduce Steps to reproduce the behavior:

1. Disable "Quick Menu on hotkey" in Sound Switch settings.
2. Launch Playnite Fullscreen
3. Switch playback device with hotkey
4. Audio disappears, and can only be enabled by restating Playnite

Expected behavior I would expect device switching to work the same both with and without Quick Menu enabled.

Additional context Playnite has the option to switch output API between WASAPI and DirectSound. WASAPI doesn't allow switching between devices at all in this situation which is probably an issue with Playnite, but DirectSound works as long as Quick Menu in Sound Switch is enabled.
