Resident Evil 0,1,3, probably other games which don't run at full speed

What went wrong?
besides all the good things introduced with the merge of fifo-bp branch in master it also caused the issue that if a game does not run at full speed (e.g. runs with 27 FPS instead of 30 FPS) this causes intermitent sound cutouts which either get worse if FPS drops further or get better if FPS increases.
What did you expect to happen?
Sound should synch with video stream instead cutting out
What steps will reproduce the problem?
Start a game with performance issues and use recent build

Are you using Vbeam with the RE games that need it and which audio backend are you using with those?
I think ideally you should be using VBeam and OpenAL audio.

in my own testing, 0 and 1 need xaudio2 and vbeam, 3 should be smooth but the beginning of the game leading to the factory scene will be slowed no matter what setting.

The audio in the RE games works quite differently to most games. This is why there were a lot of audio problems specific to these games. They use a streaming buffering technique similar to how YouTube plays videos, by sending the audio as needed.
The OpenAL backend can timestretch the audio to minimise the audio cutting out but there is not much we can do beyond this. The issue exists because of how the Resident Evil developers chose to code their game.
