No, it was the DSP's "mute" flag getting opposite-toggled and desynchronized from the "pause" function.

ahhh... so after the car is started the DSP is muted, and if you hit the pause button, it unmutes, but it's paused, so no sound, and hit it again and it's unpaused but muted? Interesting.

This has happened since day one with me and i thought a bunch of people had reported it. no?
