Comment(by markspieth):

 couldnt make it happen. So i'll guess at the problem.

 3 uses a different approach limiting the total buffered audio to 2 secs.
 Note mm spams the audiooutput layer until it cant take it anymore. In my
 case with 1.5M buffer + alsa sound buffer this was 8.7 seconds. so
 changing speed took 8.7 secs to be apparent.

 down side is 2 secs limits video playback and audiosync adjustment
 possible, though that much should be ok I would have thought.

 alternatively, we could create an interface that mm could use to limit its
 buffer usage, and restrict it to mm only. you choose.

 If ok Ill add settings for the maxaudiobuffertime param.
