PlatformPlayer: Attempt to load audio files with empty contentType

In "Gangstar Rio - City of Saints", it appears this empty type
is actually used by WAV files, so let's try opening streams that
come with those empty strings, they might contain one of the
supported media formats.

As opposed to printing "No player for: " on the console, Gangstar
Rio now plays SFX correctly. Jurassic Park on the other hand,
fails to open its very first audio stream as either MIDI or WAV.
