I've tried ATI's MMC, Snapstream and a couple of others all with the same result. No audio.

Signal is from DirectTv stb into s-video in on radeon 9200 vivo card and looks great on screen.

Audio from stb to external usb sound processor LINE IN, Onkyo se-u55, sound is great.

I have recorded music from tape deck in this way with excelent results using Cool Edit Pro.

In the setup dialog, the Onkyo is seen and selected. I suspect it is a configuration thing. I have found no postings with this problem. Hoping for some expert advice.
