Try using a different outlet or a surge protector to minimize interference from the powerline adapter.
I currently rely on a TP-Link WPA8360 setup to connect to a spot that’s out of range (my computer is there). After using the powerline adapter for some time, I noticed it was disrupting my speakers and headphones. I think switching to Wi-Fi might help, but my room is also a dead zone. Moving my computer or router isn’t an option because they’re occupied, and I can’t remove my modem or drill through walls due to my landlord’s restrictions. Some suggest using surge protectors, though others warn they could interfere with the powerline connection.
Avoid connecting the powerline adapter directly to a surge protector. Instead, use a surge protector with a mains outlet and then connect another device to it. This method doesn't ensure improved sound quality. The electrical "noise" from the adapter might be intercepted by the analog cable linking your stereo output/input to your amplifier speakers—this cable can function as an antenna... though typically these audio cables are coaxial, with a signal wire inside a grounded wire mesh.
Consider using a ground loop noise isolator if you're concerned about interference in your audio setup.
