Sound stutters (GameCube) [Thread corrected]

[CalebeCastro]

Sorry about the last thread. So Im having bad sound stutters in 2 games (Harry Potter III and II, all my games) wich its causing bad FPS. I am using Dolphin 4.0 only, and these are my specs:
GPU: GIGABYTE GTX 670 DDR5
RAM: 8 GB DDR3
CPU: Intel i5 3.3Ghz (Srry, I really dont know the model I know its good)
HDD: 1 TB
OS: W8 Pro
Font: 600W
For HP II I've manage to fix the sound stutters by changing the DSP settings to DSound and the other Recompiler.
But with HP III Ive tried everything, but the sound stutters remained. Searching the internet I did not found a fix for it, so can you guys please help me? There is an particular settings in DSP, Emulation and/or DSP to fix this? Is there a patch? They say that this game its not playable, but there are NONE possibilities to make it playable? Please help.
Im currently using default settings so you help me.

You aren't using LLE audio are you (the recompiler or the interpreter in the DSP settings) are you? You should just use HLE audio (the first option). If I recall correctly, the Harry Potter GC games are actually very demanding on the CPU. 3.3GHz isn't enough. We still need your exact model (yes, it can make all the difference between not being able to run some games fullspeed or not). Use a program called CPU-Z and post a screenshot of the info it shows.

At any rate, please do not use 4.0. It's one of the slowest versions of Dolphin out there, probably. Use the latest development revisions here (the 4.0-19XX builds) : https://dolphin-emu.org/download

The newest builds should be faster than 4.0. See if that helps at all.

Ops, thats my REAL CPU, srry: Intel Core i5 760 2.8Ghz.
By using the 4.0-1995 version, HP II it´s perfect VPS: 60 - FPS: 60 - 100% all the time, of course there are some minor bugs that can be ignored, but HP III, does not even shows the movies right before going to the menu. In the 4.0 version it did. You could play, but because of the sound stutters the FPS got bad, and it become unplayable. It seems that this sound stutters was fixed. But, how to fix this? It freezes right after the pre-loading to the intros.

Maybe the HP III dump you have is corrupted.

Okay, by changing some graphical settings, I've made it. All intros are being normally displayed, with good FPS. Sound stutters are gone, because of the Dolphin version. But sound still glitched. It replaced the stutters (HE-E-L-LO-O) with something like a robot with bzzzzs (HEEEELOOO). When I changed the sound Backendand to OpenAL with 30 latency, the bzzzs are gone, but its still slow. The game is fully playable (with 10 or less FPS) but because of the sound issues it got a real bad FPS. I believe there is an way to fix this. But Im no expert, so I will need your help.

This game is not only really demanding, but it's a dualcore unstable game. I'm not sure if you can actually play it full speed on your computer.

Yeah, I've tried everything. Even Overclocking. But nothing. Hope one day, they'll fix it.
