I can't get mine to work. I haven't tried it with recording gear, but with an Aiwa stereo and a Panasonic VCR, recording into a Zoltrix Nightingale optical in. It seems to be putting both channels into the left channel, and in CDWave there is nothing on the top half above the center line, and nothing but huge distortion/overloading in the bottom half. I tried switching plugs around, making sure it was plugged into its own outlets with the computer and stereo plugged into separate places, but it didn't help.
