I've been away and really busy working so haven't posted for quite a while, but I'm after some help.
I have been given an old behringer fca 202 firewire audio interface, to use with my desktop for production. i know its old and not great but it was free and i figured better than the headphone out
Anyway my problem, on my friends (erm..) hackintosh, it was working absolutely fine, sound output etc.. all good.
Ive got it home and plugged it into my desktop and went to test with headphones, the output is weak, no bass, and really tinny & has almost like an echo on it.
i have tried this with akg, aiaiai, and some crappy earphones and they are all the same, i have also tried changing the samplerate, with no difference.
HOWEVER.... when i plug in my old knackered hd25's the sound is good, just lacking in bass.
any ideas would be greatly appreciated.
desktop specs are: mac pro 1,1 , 16gb ram, 2x2.66ghz quad core intel xeon.
