OnAudioFilterRead issues on Android?

Are there any known issues with custom AudioFilter components on Android?

I made a small audio sequencer that i implemented using OnAudioFilterRead for performance/latency/timing reasons. It works like a charm in the editor and in a webplayer build, but i have no sound on android.

Any hints to possible causes are appreciated.

Seems to be common problem!

There was old problem in unity 4 something and got fixed, now it is back.
