If the input audio is L/R channel use two resistors (1K ohm should work, not 
critical regardless as it's only for isolation) one for the left channel and 
one for the right channel to combine the audio to a single line.  Use the 
other wire for ground.

On the input side simply connect both inputs to the same wire.

                    ~1k resistor could be as high as 50K and still work.
L out put  ---||||---                ---- L input
                             |  -----  |
R out put  ---||||---                ---- R input

ground     -----------------------

BTW it might work without the resistors but being an old time radio tech 
(back to the vacuum tube days) I try to be conservative as the lack of 
resistors could induce some distortion.  Unlikely to cause any damage 
regardless.
