Hello all. This is my first time so be gentle :D

I am making a audio switch with 4 audio sources and one output to speakers.
To do so i will be using either pic or atmega chip and TQ2 5V relay.
To simplify I made a picture with only one input.
When relay is on pin 3 and 4 are connected for right channel and when off, 3 and 2 are connected.
Question is, should i ground the audio source (pin 2) when the relay is off or just leave the pin unconnected?

All help appreciated. Even on my relay choice :P
