Configure boot volume vs max volume?

I tried to find a good place for it, but ultimately I think just making the change in dynamic_mixer.h is better.

ha. Always go with your first guess.
Tested and works like a charm.

Want a PR, or is this something you plan to add yourself since it’s so small?
Where would documentation for a new valid define feature go?
In the official OS7.x release thread when it’s made?

Yeah, I usually read through all the commits when creating the new release thread, and then I try to update the CONFIG_TOP wiki page from that.
