noise from my laptop? My laptop has a Microsoft High Definition Audio Controller, and when I check the control panel, I see that it lists Digital Output Device (SPDIF). Only problem is it appears that my only audio out option is the 3.5 mm headphone jack. I use a cable with the headphone jack on one end, and the other end plugs into the right and left channels on my Onkyo receiver. If I am correct, SPDIF is a digital signal, but how do I utilize that? Is there an adapter or trick to this?
Also, when I have my laptop plugged into my AV receiver, I get a tremendous amount of humming noise. This only happens when the laptop is plugged in, regardless of whether it's plugged into a surge suppresor or not. However, considering how cruddy laptop batteries are, if I don't want to be infuriated by the laptop cutting off in midsong, my only choice is to leave it plugged in. How do I get rid of this loud humming?
