I'm really not sure this is a OS X issue, software issue, or hardware issue... I'm using a Sound Blaster Extigy as an external sound card for a DJing setup. It's worked pretty well so far with a windows machine (I don't make a ton DJing, so I don't buy top end gear yet, it's more of a hobby). The thing I had to do in XP, though, to get it to work properly was I had to go into the control panel and get it to play as a 5.1 channel setup. Unfortionatly there's no option to do same in OS X. But that's not the only problem, the problem I have right now is there's no way to get any sound out of the main channels. I can only play sound through the headphone output of the sound card. It sounds pretty decent through the headphone output, but that's not a viable solution, I need to run the channels to a separate mixer. So that leads to my question...what am I doing wrong? Is it something I need to tinker with in OS X to get any program to play through the main outputs (this includes iTunes, quicktime, etc...they all only play in the headphones of the sound card). Is it a hardware incompatibility? OS X recognizes the Extigy, so I don't believe that's the case. Is it something I need to adjust in each individual program? I don't really think this is the case, as it's a global issue. I'm really leaning towards it being an OS X setting I'm missing somewhere, so I'd appreciate any help. Now, before you ask, I have unplugged the headphones! I only recently plugged them in to troubleshoot. I have also rebooted both the sound card while plugged in and the macbook pro while it was plugged in. I'm really leaning towards it being a missed setting in OS X somewhere. Like I said, the sound card didn't work properly in XP either unless I went into the control panel and adjusted it to 5.1. Any advice would be greatly appreciated.
