Harteex was working a bit on adapting raw audio buffering for the Dingoo.

Here comes a library and a simple sample how to play Ogg Vorbis Audio files. It plays test.ogg in the same directory as the executable. Exit with Start+Select. Sound is not perfect, because it needs buffering!

This is just a basic sample.
