i bought this USB soundcard and i use it with a Wavemaster MX5 5.1 dolby surround system & 2 rear speakers (2way speakers from last setup in car)
i'm still testing it outside my car. it works great!! it sounds like in cinema..
for carpc i'll buy the via epia m10000, but i think i'll use the creative usb soundcard! i really like it..
before this soundcard, i had the terratec aurean usb.. it sucks!!
i know.. i didn't really help you! but i can say.. i like the creative soundcard!
i don't know how it sounds over line-out to receiver..
