Alsa and SBLive background noise

I have a problem with ALSA and background noise. whenever the sound plays, I get this very annoying background noise if I check the sblive analog/output jack (using gnome-alsa-mixer) I cannot uncheck this because suddenly my master volume will only control the front speaker, which means the volume control becomes useless. It is especially apparent when I am watching movies and it is during the dialog, and when a song fades out, when it becomes more prevalent. This alone has got me wishing for OSS because I never had that problem with OSS. I have googled to the ends of the earth looking for an answer. It seems to be a recent phenomenon because I have seen people complaining about the same with Mandrake 10. Does anyone have information on how to get rid of this noise.
