[BUG] Duplication of Audio Output Devices

[spgls]

Describe the bug
A non-critical bug that can create a lot of sound output from an application. It can't happen by accident - a certain sequence of actions (and possibly conditions) is needed. May cause performance degradation, but does not affect the application functionality

To Reproduce
Steps to reproduce the behavior:

1. Install Moosync either through Deb package, or through Flatpak
2. Start Moosync and do a initial config
3. Add at least one song to the play queue
4. Reload Page with F5 button - Each reload will create one additional audio output

Expected behavior
Reloading should either have no effect on audio devices, or reloading should remove inactive devices

• Sound Server: PulseAudio 15.99.1
• Version: Both Flatpak and Standalone 10.3.2

Playback is performed through the last created audio output device.
