The DVD only has RCA jack outputs. It plays fine through the TV but
when we try to play it through the Aux In on the stereo it just
generates a buzz. The TV has no audio outputs. I think that we have
some mis-matched impediances.


Buzzing indicates a ground loop. Mismatched impedance will manifest
itself as weak/loud/distorted sound.


Thanks for the pointer. In this case the DVD runs off of the inverter @
120V AC and the stereo runs off of 12V DC. Are you suggesting placing an
isolation transformer on the DVD player?
