Hey guys, i have a CT1330A rev 4. James contacted me when he was requesting people with SB Pro 1's to submit them to scientific testing.
Turns out that my card ONLY outputs in mono. I tried different cables i made sure the mixer was set to stereo and i still have that issue. Both FM and PCM come out of one channel only. To dissipate doubts, i ran a game with support for dual OPL2 and FM comes still out of one channel only. I'm using a behringher mixer so its pretty easy to notice only the left channel works. I tried removing the jack just slightly and soon enough it reverses, L becomes silent and R outputs.
I don't know if this is any configuration problem in the card, like jumpers or so.
I hope i don't have a bad card. I can desolder the jack socket and solder a brand new one but i don't think this is the problem.
