Sorry, I'll try to explain.
I'm using ver 236 and there IS audio but it's broken. The music seems to slow down, speed up, and then slow down again until it plays completely incorrectly. There don't appear to be any issues with the sound effects, that I can tell.
Since it's hard to explain, try booting it up again, listen to the music, and compare it to the soundtrack:

It should be obvious what the issue is. I also went ahead and loaded MAME 220 to check if the issue was there and it is. I must not have noticed before.
I'm on an Intel i9 @2.40 GHz, so it shouldn't be an issue with my CPU. If there's any other info you need from me, let me know
