I have watched videos about how to do this, read about it as well. I have headphone input cable which ends with two RCA cables. I insert this on the computer headphone and lineout (EXT) outlets on the cassette deck, set the player to EXT whereby I can hear my MP3's playing but when pressing record on the Cassette player then after listening, I get nothing, simple silence as though nothing has taken place. Any suggestions?
FYI: Stereo System is a Technics RSHD505 thank you
