Final Fantasy Tactics: WOTL Garbled/Stuttery Music

[breakstherepetition]

Hello!

I'm currently running v1.4.2 on Windows and trying to play Final Fantasy Tactics. The game itself runs just fine, but the music is consistently garbled and poor quality. I've spent the last week trying every option in the settings I could find in an attempt to fix it to no avail.

So far, the only option that has any impact on the sound quality has been changing the audio backend from Auto (which ends up just making the audio even worse).

I recorded some audio dumps so you can listen for yourself:
clyp.it/sz5ikwt0
clyp.it/aqsonilz

The music is garbled at the same points in each track every time, which leads me to believe it's happening independent of system performance. I've also wondered if maybe my .iso file was corrupt, but I tried a different version and had the same issue.

If anyone has any ideas, please let me know. Thanks!
