(Linux) audio_sink option should not change your default audio output

### Is your issue present in the latest beta/pre-release?

This issue is present in the latest pre-release

### Describe the Bug

This is my audio setup before starting sunshine stream:

As you can see I have set my default audio output to "Virtual Surround Sink". I have set sunshine to listen on my equalizer sink and there is no `virtual_sink` set in my config. `audio_sink = effect_input.eq10`

After starting sunshine stream it looks like this:

Sunshine is listening on my equalizer sink which is great that what I wanted. But at the same time it created 3 additional virtual sinks `sink-sunshine-surround71`, `sink-sunshine-surround51` and `sink-sunshine-stereo`. It also set `sink-sunshine-stereo` as default audio output and now all application are outputting to `sink-sunshine-stereo` while sunshine is listening on my equalizer sink where there is no sound coming through. This make configuring `audio_sink` useless because there will be no audio going to your sinks.

To fix this i have to set manually "Virtual Surround Sink" as default output device after starting sunshine.

### Expected Behavior

Stop creating virtual sinks `sink-sunshine-surround71`, `sink-sunshine-surround51` and `sink-sunshine-stereo` when you configure `audio_sink`

or

Stop setting `sink-sunshine-stereo` as default audio output when you configure `audio_sink`

### Online logs

_No response_

Start by tracing the Linux audio_sink handling and the creation of the sink-sunshine-surround71, sink-sunshine-surround51, and sink-sunshine-stereo devices. Reproduce the configuration with audio_sink = effect_input.eq10, then verify that starting Sunshine does not redirect the system default output or leave the configured sink without application audio.
