Thread: Sb Live 4.1 and XM Radio

First of all - this is my first post - so I did do some searching but couldn't find anyhting on the topic. I just finished up my carputer install today. I'm running into an issue with the SB Live sound card doing 4.1 in XM Radio. I get 4.1 fine when running just mp3's - but when I switch to Frodo XM, it goes 2 channel only. Any ideas or settings I should look at? I'm pretty puzzled. The only thing I can think of is that the line is is fed right back out and hence the 2 channel stereo output - but I wonder if I can get it to do the 4.1 so I can have front/rear output on my amps? Any help appreciated. Thanks!
