tests: Fix automated audio tests on Windows and Linux

Browse source 
If a specific audio driver was requested for testing, don't loop over all drivers in the init, open/close, and pause/unpause tests.

Additionally, drivers can fail if attempting to open an audio device when no underlying output is present, which is a valid case if the system has no audio hardware available. Check for the presence of audio output devices before attempting to open them.

Fixes automated tests with various drivers on Windows and Linux.
