Mixing 4 audio channels to 3?
You still have the signal go to the non-inverting input.
The current version of the drawing has signal going to the inverting input
Are cap values reasonable? I added C8 & C9 out of habit of seeing in other
designs. Values for these?
I worry that the RC time constant would have the reference be not at the
1/2 way point while C8 charges on powerup.
Suggestions?
I don't see a C9.
That means you're not looking at the right version of the drawing. Copy &
paste this into a browser:

Might do something not so good to the subwoofer.
