Sengoku Musou 2 HD Moushouden with Empires

Hello!
I'm a newbie over here and I've been trying out this game. So I've noticed that this game has been noted as Intro in the compatibility section and after testing it, it runs well in game. However there is an issue with the game in the sense, the audio gets completely garbled when the fps drops or rather most of the time even when running at 60 fps. I'm using RPCS3 0.0.6-7985 Alpha and I've seen this game work well with older versions. However from what I've tried searching through older versions get merged with the master file in github making them unable to be downloaded. I'm relatively new to github as well. The version that did work was an October 2017 update of 0.0.3.

Specs:
Intel i7 5500u
GTX 950m 4GB Dedicated
16GB Ram
1TB HDD

The specs for the one I've seen it working was
Intel i7 4700mq
GTX 860m
8GB Ram

So I don't think the garbled audio was an issue with my hardware but rather definitely with the fps dipping. The weird thing was the video I saw had their fps dipped but the audio's pitch was higher and normal. I've been trying to find the reason behind this but to no avail and I don't understand how the much older version supported this game than the current ones.
