Had to sell a large part of collection. Question on modded system

Hi all - I have my original Saturn and it works great for standard discs.

I had to sell off a big part of my collection. My system is modded and I have backup discs I will likely be playing more of. The issue is that the audio is janky on some of them. Ie the games run fine but the audio skips and then just goes off

If I adjust my potentiometer does anyone think there is a chance this fixes the issue? I have verbatim discs so I probably won’t be able to get much better quality ones.

Any thoughts appreciated!
