I just installed simvibe with an extra soundcard and, for some reason, the left "rear suspension bumps" do not work. I am still waiting for my transducers and amps, but I was able to test everything using my headphones.
The test tones work for each corner using both windows and the tester in simvibe. I'm getting output at each corner in the game too. -But when I was listening to the rear left and right, the left was almost silent on curbs where the right sounded like, well curbs. Both fronts make curb sounds when either of the tires are rolling on curbs and it sounds convincing from 3 of the 4 corners. The left rear though? Nope. After testing each effect individually, it seems the "suspension bumps" are not working on the left rear, only the left rear, and only that specific effect.
I downloaded simhub (the free software) and everything works as it should. (although the curb effect seems pretty generic, it is localized for each corner)
Has anyone else had this issue, and what was the fix?
