I purchased a pair of m-audio studiophile BX5 monitors and hooked them up to my m-audio 410 firewire audio interface. The problem is that I'm only getting sound out of one of the monitors. The TRS inputs are running from the monitors to the analog 1 and 2 inputs. Apparently the analog 1 input is doing its job, but no luck with the second. I tried plugging the trs cables into the line inputs, but had no luck with that. Can anyone advise me as to what I have to do to get sound out of both monitors?
