Buzzing on Macross Scrambled Valkyrie Soundtrack

[/classicSNESmini]

As the title says, there’s a weird buzzing noise that’s replaced some of the soundtrack’s notes on the Macross: Scrambled Valkyrie rom on my Snes Classic. It’s quite loud, noticeable, and off-putting.
I checked some YouTube playthroughs and it isn’t just in my head.
Weirdly, this has never happened before, and the only thing that’s different that I can think of is that I found a new Snes Classic to replace my old, damaged one (and reuploaded all my games) since the last time I played M:SV. It might be a newer/different Classic model because it didn’t come with a USB power plug or a poster like the first one.
Are some Snes Classic consoles known to have audio issues?
Does anyone know what’s going on here?
*Also, I tried deleting the rom off of hakchi and uploaded a “newâ€￾ one and that didn’t fix the problem.
