Thanks for your reply. I think that mono refers to the "snd_playfile" command, however i'm using the "snd_loop" to play my files. As far as I can tell from the manual it shouldn't be playing in mono with that command call. I also changed the balance controls thinking that was the problem, no luck.

I haven't been able to find mention of that flag in the manual, i'll keep checking though. Thanks again. This is quite a mystery...
