“I have this connected to my TCL 4K Roku TV via the 3.5mm aux cable. Audio works, but I hear buzzing/white noise when I put the TV on mute or whenever there is no dialogue playing. Any idea how to fix it? This TV does not have RCA audio output.”

Have you tried to hook it up using an optical cable instead? You can pick up a cheap 4-foot Dynex optical cable from BB for less than $5. I would try going with optical audio and not waste too much time trying to figure out the cause of the interference and noise using a 3.5 connection until you've tried optical.
Sorry, there was a problem. Please try again later.I originally asked this question. I connected the soundbar to my TV with a digital optical cable and it resolved the white noise issue.
Sorry, there was a problem. Please try again later.I agree with kcasey. Buzzing is usually caused by the ground wire not connecting correctly. A new cable should be intact at all points, thus eliminating the buzz. You can also try jiggling the cable at either ends: grab the cable at the point where it connects to the connector and push it slowly in different directions, working it around to complete a circle, to try and find the problem. Do this at both ends of the cable if necessary. If the buzzing goes away, even for a second or two, you know that it is loose and damaged, and needs to be replaced.
