SDL: Select audio device (#2403)
* Initial Commit Added Device logic to Sinks Started on UI for selecting devices Removed redundant import * Audio Core: Complete Device Switching Complete the device switching implementation by allowing the output device to be loaded, changed and saved through the configurations menu. Worked with the Sink abstraction and tuned the "Device Selection" configuration so that the Device List is automatically populated when the Sink is changed. This hopefully addresses the concerns and recommendations mentioned in the comments of the PR. * Clean original implementation. * Refactor GetSinkDetails
