The Cable worked fine up until early November. A couple of days after the problem first began, I was able to hear my bass guitar while in Rocksmith. I didn't do anything to try to make it work. It just did that one night. Since, it hasn't worked properly. Thanks for your response. I start Rocksmith and there's no sound. I do Alt-Ctrl-Del to get out of the game while it's still running. I look at the volume under Levels and the Cable is muted. I un-mute it. Sometimes, it will change back to muted in a split second. I see it happen. Other times, it doesn't happen quite so quickly. I get back into Rocksmith but by the time I start a song, the bass is muted. Other times, I can actually play a few notes before it goes quiet. Rarely, I am able to play most of a song before it goes quiet. I do Alt-Ctrl-Del to get out of the game while it is running to check the Levels again and it is muted. It's changing on its own for whatever reason. I tried the Beta option through the link that you provided in your response but it didn't fix the problem. I followed the steps. Maybe it's the Cable. Do you know where to purchase another one other than through Ubisoft?
