Super smash Bros Melee, Super Mario sunshine, LoZ Wind Waker, Luigi's Mansion, Kirby air ride, Pokemon Battle Revolution, Pokemon XD, Pokemon Colosseum, etc..

Game ID?
irrelevant

What's the problem? Describe what went wrong in few words.
Under dolphin's free Dsp lle rom and my real one that I dumped from my Wii, the samples are incorrectly ouputed and have static in them

What did you expect to happen instead?
No annoying static in sound

What steps will reproduce the problem?
Under DSP LLE listen for satic coming from the sound, I found LoZ : Windwaker was the easiest way of reproducing static in the sound

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
Builds since Dolphin-4.0-1970-x64 have the issue

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Yep, all of builds before the DTK merged into master did not have the issue
Builds 4.0-1963 and below work fine

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
irrelevant

Are you using the 32 or the 64 bit version of Dolphin?
64

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
The DTK rewrite is the known culprit for this issue.
