Thanks "CJ". Didn't work. Reckon I'll just keep tweaking away. What also surprises me is that with the SB 128 VIBRA, the 'continous engine sound' option under preferences is "greyed" out, so one cannot even select it. But that's secondary as, I have selected 'sound blaster' & still no sound at all. At least the on-board sound card (disabled now)used to give me the voices (only no continous engine sound). With absolutely no sound, the program is a real bummer!!!
