Just to contribute that I use ethernet over power plugs with no apparent problems. I have perfectly clear sound with no interruptions.
FWIW, I did considerable research before trying this and found that there were mixed opinions - some had success, others had experienced problems. My conclusion was that the problems are caused by other 'noisy' devices on the circuit - fridges (with compressor motors) were notably problematic. This appears to be the case with the original poster, who stated that better results were achieved on a different socket (circuit?). My conclusion was that if it was the powerplug itself (or the technology), the results wouldn't change on a different socket/circuit. Anyway, I took the plunge and bought the best powerplugs I could find and it worked for me. As success appears very circumstantial, there are no guarantees with this.
In case it's of interest, I use TP-Link AV500 units.
