easier to read and reply to.  This is particularly important for large

This is something you'd need to change in alsamixer and the control
naming standards.  None of this stuff is really supposed to be directly
edited by normal users, they should mostly be using a UCM configuration,
so at the minute this is essentially bikeshedding.

I think you're looking for something that exports routing to userspace.
Doing that would also help with reducing the faff with naming rules.
Currently nobody is working on that but I think people would be very
happy if someone were to work on it.
