Since you don't seem to follow dolphin, I'm going to go with a general explanation. Please don't think I'm talking down to you. Regardless, I agree that the answer "Just OC more" is a poor one, in fact, I think there are quite a few things that could help you out.
One: The sound skipping is due to an upgraded HLE audio setup. It skips when the game slows down because that's the accurate way to do it. The old system as used in that video. Audio was always full speed, but it causes a lot (hundreds) of games to crash, lose audio, or have other severe issues. I think your game should be running full speed, so here are a few tricks.
Using OpenGL on a Nvidia is faster. Mario Kart Wii was also faster on a set of development builds, for example, https://dolphin-emu.org/download/dev/6cece6b486670dd149c827053a84754c98397ccc/ is about twice as fast for me on OpenGL backend. It was unfortunately reverted due to causing issues in the D3D11 backend, and will have to be reworked before it sees Master again.
Make sure you enable the "Vertex Streaming Hack" under hacks. I believe the game will run a lot faster for you. If it doesn't, disabling format change emulation can also be a nifty speedup at the expense of some graphical glitches. I hope this helps you out, if you have any other issues, I'll be watching this thread. Cheers!
I hope this is a more satisfactory answer for you!
