Audio during cutscenes in Scooby-Doo! Who's Watching Who? is out of sync and distorted #13872

Open ghost opened 3 years ago

Emulation speed fluctuates wildly but never seems to reach 100%, which leads to the audio sounding horribly crackly and distorted. It also doesn't match up to the cutscene at all. I've tried it with Vulkan and OpenGL and at x4 and x1 resolution. Audio during gameplay sounds fine.

@Tiberius1437 are you using the latest build of PPSSPP?

ghost commented 3 years ago

Yes

What device is this on? Does frameskip help? If you fast forward does it run faster?

If the game can't run at 100% on your hardware, sound will be broken and distorted. This is because games produce tiny bits of the audio is they do other things, so if anything false behind, audio is always the most obvious thing.

Maybe there's something fixable making it slow, but I'm just trying to identify if there's multiple issues here or not.

PC

Does frameskip help?

Setting frameskip to 1 breaks it entirely. The audio is still playing and just as distorted but the cutscene freezes and then skips to the end.

If you fast forward does it run faster?

Yes it physically plays faster but the audio is still distorted.

This branch made it far worse. Now the FMV is skipping and stuttering. The audio is still broken in exactly the same way.
