you need a 4PDT or two DPDTs. Diagram shows one channel only

You want the switch to bypass the volume control? In the first diagram below, the pot still loads the input, even when not used.

If you want to totally disconnect the pot, you'll need a 4 pole 2-way switch (or a separate DPDT for each channel). Second diagram shows this for one channel.

Cheers - Godfrey
