Allow Linux users to choose an audio input for the actual soundless Screen Share issue

Currently the Screen Share works well on Windows, with a workaround on Mac and Soundless Only on Linux version with the only existing workaround is to make everyone in the call to listen the app audio and your voice at the same time (creating loopbacks locally), but it's not always the case where everyone wants to watch and be on call at the same time, but just on call or just watching and be obligated to be on both is a pain.

That said, one easy, not ideal, temporary but good solution would be letting us choose from where the stream should be getting the audio from. A Linux user can create a virtual audio device and redirect audio from programs with simple steps. These devices could then be choosed from the Discord UI if you let us to and solve the above issues.

Thanks for the attention.
