What component to use for audio signal switching?
https://electronics.stackexchange.com/questions/95598/what-component-to-use-for-audio-signal-switching
Now, I need to switch audio signal obviously and I need to do it quietly (both physical silence and electrical silence). Please note that the signal is line level throughout most of the build, except for the input which is much lower. I will probably have 2 or 3 loops before the preamp so those may not encounter line level signal.

The switch portion of the basic SPDT relay is shown as a switch that consists of a pole which can be switched to one of two throws. The throw that the pole connects to when no current flows in the coil is called the normally closed (NC) throw. The normally open (NO) contact is - well, normally open. A spring holds the switch in this position.

This is one way to switch audio signals without the use of a mechanical relay. It takes the input of two buttons to switch between two stereo audio sources. ...

Many of them are "clickless"; they change resistance slowly enough to prevent an audible click caused by either a little DC on the signal, or a mismatch in signal phase, such as switching from the middle of a positive peak in one signal to a negative peak in the other. Small DIP or SIP reed relays are another option.

The voltage that 4066 can switch is limited by its supply rails. If the switched signal extends outside of the supply rails, the 4066 will clip it. A relay can switch considerably higher voltages. A mechanical relay would introduce practically no noise into the signal that it's switching. The 4066 will introduce a small amount of noise.

I need to switch stereo audio input (i.e. Ipod/Iphone level signal) from source "A" to another "B". The vehicle switch is effectively an SPST. So, to switch the two channels, I need to use one DPDT or two SPDT relays to swap the two channels. It would be a mechanically robust mobile solution...

The logic-level for switching will depend on the supply voltage you use, for example, if you use 5VDC to supply the chip, then you'll need a logic-level signal of <= 0.8 for a low, and >= 3.5 for a high. See the datasheet for details. Audio signal #1 would go the #1 switch input and audio signal #2 would go to the #2 switch input.
