This reverts an earlier change 4aeec2da39fce4de9b07b694d59fd308ffb3d491
Instead of returning 0-filled buffers after EOS from AudioTrack we do this
work in AudioOutput instead. That way the EOS signal (0 frames returned)
is preserved in AudioCache which otherwise would lead to a heap size overflow
filling everything with zeroes.
