Missing sound effects in Wonder Dog

Original [issue 234](https://code.google.com/p/genplus-gx/issues/detail?id=234) created by superballena on 2012-07-05T16:47:15.000Z:

What steps will reproduce the problem? Just start a game normally.

What is the expected output? What do you see instead? Sounds for skidding, crouching while running, drilling through the floor, earthwuakes and tornado power ups are never pleyed.

What version of the emulator are you using (official, SVN revision,...)? 1.7.0

Please provide any additional information below (Emulator settings, Console setting,...) US version 2.0 BIOS

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!
