Thanks so much for looking in to this!

Here's the skipping in action. It skips to frame 60 regardless of where you place the audio event.

You can hear how the audio event is triggered at frame 60 and subsequently overlaps the second audio event which is triggered at frame 86.

I'm working with some music in Spine, using 4.1 on an M1 Mac. When I try to play the timeline the playhead skips forward a variable amount of frames (it could be 5 frames, could be 60, haven't noticed any correlation as to why) and starts playing the audio from that point, meaning I can't sync up the audio with animation and I'm missing that first bit of the animation.

I've done a bit of testing on different versions and platforms to try to narrow down the issue:

• Same behaviour whatever the playback mode (continuous, loop, manual loop)
• It happens in any Spine 4.0 and 4.1 project with mp3s and wavs (haven't tried any other sound formats yet).
• Spine 3.8 seems to work okay
• It's only happening to me on Mac, sounds are working fine for me in 4.0/4.1 on Windows and Linux using the same sound files.
• Tried completely reinstalling the Spine launcher
• Tried both the Apple silicon and Intel installations of the launcher
• Timeline will play fine with regular events, it only happens when there's audio in the event

Anybody else experienced this?
