Fwiw, I may have mentioned at the FOSDEM beer party that this feature
was on the to todo list for the hardware use case or scenario manager.
Although being a beer party we may not remember discussing....

This would likely be quite time consuming wrt to embedded drivers due to
the complex audio hardware requirements of modern mobile phones. There
are numerous hardware routes with different inputs and outputs and they
are used in different combinations depending on use case.
I think it's probably quite reasonable to do this for most PC sound
cards as they are often simpler in terms inputs/outputs.
