@devgianlu, would you be able to provide a method that is generating a stream of raw PCM data that I could use for testing?

So farI am only able to create a finite byte array that does lead to an audible tone if I use AudioTrack.MODE_STATIC in AndroidSinkOutput. The test in fd4c3a0 does pass with AudioTrack.MODE_STREAM as we actually need it, but then I do not get an actually audible tone during the test.

Hey @devgianlu, nevermind. I found a viable solution.

Awesome! Hadn't time to have a look. Next thing on my schedule is the UI.
