i'm think about getting some speakers. i'll probably get the Altec Lansing AVS500. it's a 4.1 system and i can get it for pretty cheap. i was just reading a speaker review at insidemacgames.com and it said that OS X supports surround, but the headphone jack can only output 2 channel sound. i'll probably still go for the AVS500s, because 4 speakers would have to be louder than 2, right? and is there any way i could get the use of all 4.1 channels from my Mac without buying any expensive hardware? i'll probably still get the AVS500s in a couple of days, but i was just wondering about the future of Macs and surround, and if there is any way i could get surround from my TiBook?
