I m having an Imac 24" (early 2008) with dual core processor 2.8 ghz ram 4 gb (upgraded) hdd 320 gb
i've purchase creative inspire T6100 5.1 surround sound speaker system.
it was not attaching with my that time. so i've purchase creative X-fi external sound card. it has been attached to the Imac but after a lot of settings, it is working like a 2.1 speaker system. what should I do? please help.........
