Sega CD Audio blipping on gamecube

Many sega cd games run reasonably well on gamecube, but are plagued by one main issue which is audio quality. It happens across every one of them where the audio consistently pops and is a big distraction from playing anything at all.
Seeing some support on the emulator recently, I thought maybe this could be looked into? 
I'll try and upload a video example of it later.
