Works fine with Model 1 BIOS, must be some incompatibility with model 2 BIOS 
and PCM chip emulation.

When using 1.0 BIOS, loading a state file made after the game is started with 
2.0 BIOS will also makes PCM sound disappear so it could be related to PCM RAM 
initialization with 2.0 BIOS.

From what I read, using the 1.0 BIOS is preferred since the 2.0 BIOS is 
apparently very buggy. That's why the 2.0 BIOS don't work too well in Kega 
(background music always playing when entering the CD player for example).

The BIOS aren't buggy at all on real hardware, though.

Different BIOS means that there are differences in hardware: obviously, i am 
trying to emulate a generic hardware and afaik all the docs we have describe 
model 1 cd hardware, hence why it is generally recommended to use model 1 bios.

I know one of the model 2 bios dump available on internet is bad though, but it 
will freezes immediately on boot so cannot be used anyway.

I fixed a bug with PCM emulation where the WAVE-RAM address was only reloaded 
when a channel was switched ON, which was not correct (seems like the current 
WAVE-RAM is reloaded as long as the channel is OFF).

It seems to fix a few other games beside this one, in particular Switch/Panic 
and Final Fight CD sound effects.

Yep, I haven't noticed any more problems in this game or Switch.

Thanks for fixing it!
