Extend audio tets

[macpijan]

Detect sound card and audio sink separately.

Currently our detection methods might be different for Linux and Windows. If there is no actual oputput connected, we may have PASS for Linux (we check for sound card presence only), while at the same time we get FAIL for Windows (maybe we check just for sink, or maybe Windows is different in this matter?)

This may be often confusing, and suggesting windows drivers might be missing, while in fact there is no audio device connected.

Detecting sound card and audio sink in two different test cases, would help to isolate that.

Commit: 15560f1 changes detection on windows side to detect wider spectrum of devices, sources, and sinks, which could be used as a base for separated detection (filtering speakers from audio cards or virtual sound devices)

This is step in good direction, but ideally we have separate test cases, so we detect audio card and speakers (or headphones) separately.
