Just noticed while playing Mortal Kombat that there are no sound effects when punching, etc. Music works though. The dreamcast is running through DCHDMI with a GDEMU installed. Tried different HDMI cables and different HMDI inputs on the TV. no change I have a second GDEMU modded dreamcast with analog outputs (mortal kombat works fine there), and have not tried doing any A/B comparisons with swapped components yet (would prefer simpler things to rule out before opening up the unit). Any thoughts or ideas?
