Summary 07109: cobram3: Cobra Command Laserdisc Game on Gottlieb Mach 3 Hardware AY-3-8912 sound issue sounds cut out.
Description Not all the AY-3-8912 sounds are working on cobram3. Take a look at the video on ItalianDOHs machine for reference.
Sound #9 which is the Chopper death sound doesn't work at all in the emulation.

I do not think the R2 Gottlieb sounds are supposed to be used at all on this conversion but the original roms are left there.
It is also possible is only used for 2 sounds mixed with the Ay-3-8912 not sure.

So I turned the down all to 0.00 in the volume mixer slider.

Sound test is at 1:33 mark.

Also attached is the broken cobra m3 sound test in flv format.
