Dolphin Audio / Graphics Issue

[Spunko]

I have done some experimentation on my HP Pavillion x360 for Dolphin and here is what I found out:

My games:
-SSBM
-One Piece Grand Battle
-Kirby Air Ride
-Naruto Clash of Ninja
-Super Monkey Ball

Here are the Dolphin stuff I used:

Dolphin 3:
-Smash Bros opening plays normal but when coming to battle, the audio is slow. Graphics are fine but the audio is buggy and sometimes the audio makes the graphis a little slow
-One Piece plays normal but when battling, the graphics are slowed.
-Works fine
-Works fine but when battling, graphics are slowed.
-The graphics are slow in general...

Dolphin 4.0.2:
-Smash Bros is fast but the graphics are really slowwwwww...
-Graphics and audio are slow
-Works fine
-Graphics and audio are slow
-Slow

Dolphin 5:
-Smash Bros is extremley slow
-Same before
-Same before
-Same before
-Extremley slow

Recent download of Dolphin:
-Same before
-Same before
-Same before
-Same before

All of the graphic configs have never been touched. Remained relitiveley the same. Used Direct3D on Dol 5-recent release, used Direct 9 from 3-4.

If my CPU is strong enough for Kirby Air Ride and others, why not Smash bros? HELP!
