I recently purchased a Sega Mega Drive 1 to connect to my Mega CD-II, I am using a Sega Master System A/V out, and when attempting to listen via the headphone jack no audio was being displayed via the headphones, but instead from my TV, this was not a problem with either headphones as I tested both on a PC. When I unplugged the A/V out to determine whether it was the A/V I got a faint shrill buzzing noise from headphones. The seller said that the mega drive was tested. Am I being a stupid or does my headphone jack not work?
