So my multi has been working well for a while now, but on my last boot I stopped getting sound.
Transferred to a known working motherboard and the issue is the same.
Games play fine, selector works great, just no sound.
I can hear a little squeaky garbage noise on boot, but other than that it's just static that does respond to me cranking the volume
Edit - tested on multiple cabs as well, issue is the same
Edit 2 - noticed a couple minor graphical issues in Shadow Dancer that occurred on both Motherboards
Edit 3 - Dug out my original rom board, decrypted it. works perfectly on both motherboards, seems my issue is solidified to the multi
