What's the problem? Describe what went wrong.

I am trying to play Rhythm Heaven Fever, but the input-to-audio-response lag was way too long to play comfortably. So I looked up ways to reduce audio latency on Dolphin, and decided to change the audio library from Cubeb to WASAPI.

However, WASAPI made the audio latency even worse than Cubeb, which is the exact opposite of what people online have posted. It's like Cubeb made the input lag a quarter beat where WASAPI made it lag half a beat. There must be something wrong with my setup or the latest version of Dolphin, or both.

What steps will reproduce the problem?

1. Set audio backend to WASAPI
2. Start game
3. Observe extremely choppy audio

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, encountered on 5.0-17924.

Is the issue present in the latest stable version?

No, 5.0 doesn't have WASAPI support.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

I don't know where the configuration files are stored.
