Yes, I could see how my post would be confusing...the output from the interface is not XLR as I stated it's balanced TRS...sorry about that.
Let me try again...I have the drivers installed on both PCs and a USB (output) connected to both.
Whenever I want to switch I pull out the usb connected to the interface and then plug in the usb cable from the other PC.
Does that make sense?

Makes sense, my description above is based on the assumption that everything is the way it is :)

Your description does make sense but regarding this:
To use something like this you would need audio outputs from both PCs.  If your office PC has a built-in audio interface, you would cable that output to the C-Control/similar....
 
The "audio outputs" from both PCs are just a connected USB cable...I guess what I'm asking is if there is some kind of usb hub (or something) that I could plug both usb cables into and have one usb cable from that connected to the interface and then switch which source(PC) I want to use (kind of like a KVM switch does for display monitors). 

Not that I'm aware of on the USB switch/hub.  Your office PC has zero audio capability?  That's unusual.
 
Sorry for the unnecessary detour

Your office PC has zero audio capability? 
No the office PC has a 3.5 mm integrated audio out but I don't think I would want to plug that into the interface would I?
BTW, my apologies to anyone that considers this hijacking this thread...let me know if I should start a new one please.

You would plug the 3.5mm into the control/switch unit, not the interface ... That's exactly how I have my PC sounds (other than DAW) cabled to the C-Control.
 
16x08 out 1/2 go to C-Control input A  (DAW output)
16x08 out 3/4 go to C-Control input B  (internal mixer output)
built-in 3.5mm go to C-Control input C
last inputs unused for now
 
C-Control out A goes to my monitors
C-Control out B goes to another set of speakers
C-Control out C goes to a sub
 
This is an incredibly handy setup

Oh I see, yes that makes sense...thanks Bob!

I think iConnect Midi 4+ may do what you want. I personally wouldn't use the 3.5mm headphone jack if audio fidelity is a concern.

Good point on the headphone jack.  Thankfully, mine provides both phones and line jacks.
