I was wondering if anyone could recommend me a USB sound card for a 2010 13" MBP. I've had a quick scan/search of these forums but couldn't find a similar thread. (Probably not looking hard enough ) I'd like to record my guitar on the system but would also like to use my head phones at the same time for playback. As there's only x1 3.5mm jack I was hoping to use the USB sound card for playback and I'm guessing... the built in sound will be better quality than a USB one so I'll use the built in mini-jack as an input unless you guys think otherwise. Are there any cards that lend themselves to a Mac more than others? I don't need anything stellar but a reasonable quality one would be nice. Not sure on a budget... I know that you can pick them up for a few £/$ but I'm used to a decent dedicated card (X-Fi at the moment) in my PC so never looked at the USB ones with too much interest. Just wanted to know if there were any pit-falls I need to avoid when buying one for a Mac apart from insuring compatibility. Thank you in advance and apologies if I've posted in the wrong section.
