I recently built a new PC for my cabinet. Previously I did not have any issue with buzzing noises. The backglass speakers sound fine. However, the front and side speakers in the cabinet buzz when I turn them to a normal volume. I have 2 TPA3116 amplifier boards for each the front and the sides. I put ferrites on the audio cables on each end and that did not make much of a difference. From a little research the onboard audio can have a lot of noise in it. Would a sound card or Star tech external sound card fix my issue? 

 

Thanks!

I had the same issue so I connected a ground loop isolator/noise filter to the output of each amplifier and connected the speaker jack to the output of the ground loop isolator, no more buzz.  They are usually set up for 3.5mm stereo jacks.  I think they only cost about $10 each.  I got mine from Amazon, just search for ground loop isolator.
