Sound

Hope someone can help. Am using R4 winamp plugin. When start R4 in winamp I loose sound to my sub woofer. I have a c-media soundcard with 5.1 sound with independant rear and subwoofer jacks. R4 works perfectly otherwise just no sound to sub. All the other speakers work. And works fine as soon as I exit r4.
Thanks and great viz
