All variations of 32X, even the ones not using CDs are plainly flagged and should tell you in a big red screen that "THIS MACHINE DOESN"T WORK". That means if you can do anything with it, it is a miracle and beyond loading the bios roms, nothing is guaranteed.

As per long standing rules, developers have deemed no report for such machines shall be accepted unless it is a major regression. This doesn't sound like a regression at all and has likely never worked.

This is for VGMPlay though.
The Genesis with 32X machine has that warning but VGMPlay gives no such "red" warning when attempting to play 32X audio.

32X isn't *that* bad, a lot of games are playable, it's mainly marked as NOT WORKING because a number of key titles don't run and the performance is way off (in reality the SH2s are massively slowed down by waitstates)

There's no reason audio should crash.

My mistake and I apologize for not examining your driver you reported.

Anyway, I can confirm attempting to play an entry from:
Knuckles' Chaotix 32X (GEN/MD)

That appears to be the breaking commit - on May 8, 2019, from PR#5009.
