I am planning on building a kitchen playback zone using Ropiee and an old centre speaker. Are you able to manipulate ALSA config on Ropiee or is there another way to get the output downmixed to mono?

You can do it with roon dsp.
See post below.
We didn’t make a mono button, but we did include a matrix mixer in the Procedural EQ using the “Mix” feature. It’s totally possible to mix both channels down to mono if you want:

Set it up like this:
Left, Left, -3
Right, Right, -3
Left, Right, -3
Right, Left, -3
Pay attention to Headroom Management . If you’re clipping, either make more headroom, or make those -3’s a little bit more negative. You shouldn’t have to go below -6, but it’s nicer to attenuate less when possible.

I have used the method above for years on a home built bedroom speaker that’s mono. Works really well.
