Hi AnotherTom,
Thanks for the help. I forgot to include the first part of this post where I mentioned that I am waiting on a FW card, so I can use my old Phonic FW mixer. In the meantime it would be nice to use the stock device but it doesn't work. Yes, Brand New computer with Windows 10 that supposedly comes with a Realtek audio device, but it doesn't show up. I don't get on the internet with this machine, so all of this researching, and updating and drivers, is really time-consuming and redundant, especially for a new machine, and the fact that everyone is complaining about the same issue. So, right now I can't even use the stock device for any settings like jack locations, etc. Even when I do get my mixer hooked up, I am not always using it and the powered speakers, so I like to turn them off and use the little usb speakers. Anyway, the other night I did all of the trouble-shooting that I am capable of and like I mentioned, I don't think it's the cables, they are new, they work fine with the other computers and they are no near power cables or any other cables. The thing that is weird about the noise is that it only happens with usb speakers and powered speakers. With the powered Yamahas, it is unbearably loud, but if I hook up only one speaker, using one cord (no y-cord) directly from PC to speaker, there is no noise. Also with usb speakers, the noise is there when connected to pc for power, but when connected to AC , no noise. Headphones have no noise either. What's going on here??
Thanks Again for your time
