The suggestions for parts sources are pretty much your best bet.  If you want 
to mix audio from three sources and then output to three sources, you need 
some kind of buffer amp/power amp combo.  Zener diodes are for voltage 
regulation or over voltage protection.  I'll dig around and see if I can find 
any schematics for what you want to do.
