I'm trying to use the MAX4571 essentially to mute some audio channels,

It has only ground and +?
Then you must likely bias your audio at 1/2Ub, else bottom get clipped.

analog signal range is from 0 to +V!!
+V

That chip sucks in my view,
their 'no click' switching seems to be a slow 8 ms bump.

The 74HC4053 rocks, has negative supply.

Anyways, Maxim is hard to get sometimes.
