Txs Buzkill,
tried the mono setting..and didn't like it. Mono sound files on the multi-engine a/c, don't seem to sound quite right.
I've got a set of USB headphones...on a mono file, you seem to get a sort of top end hiss or hum. This only happens with multi engine a/c. Tried everything to get rid of it, but only thing that works for me, is stereo.
Point taken on vol. and I've upped it.
