BUG - when using the speed playback, sometimes the sound is muted

Upgrade: this is happening every time to me, only at faster speeds (after some seconds), take a look at this video: https://youtu.be/ISvkTSM0hrE

If I click at he time needle, the sound comes back (back to normal speed)

Thanks for the report! Does it mute at every speed, or only at faster speeds? I haven't seen this happening myself yet and it would be great to get a copy of a sample file that causes this, if you could send one over!
