Not sure when it started to happen, but I just realized that the whine and the dump sound effects on my RB4 have disappeared...

I checked my /data/snd/DumpValve.raw against a friends' and they appear to be the same.... what do you think could be the problem?

Will do a fresh install a little later....but just wondering if anyone knows a fix off the top of their heads.

Is your engine sound volume slider set loud enough? Do the turbo sounds work in other cars?

Well waddaya know... the engine slider was turned down pretty low.....and the sounds couldn't be heard anything under around 7.0... thanks, it's fixed now
