CDDA Not Working with Optimized GDIs [SOLVED]

[pcwzrd13]

I mentioned this in the "GDI Compatibility" thread but I decided it might be a good idea to make a dedicated topic. So I've noticed that CDDA audio emulation doesn't work with optimized GDIs. Is this a known issue or am I maybe doing something wrong? It works fine with straight GDI rips but most games won't boot unless they're optimized first.

Edit: Problem solved! Solution here.
