Then these aren't playback controls either - "Bypass" would be more
appropriate.

Could you please provide the output of 'alsactl store -f <filename>' for
the case before your changes?  Your problem description seems very
suprising, you're saying that the control just doesn't appear to
userspace at all.

Again, what is actually going on here?  You've renamed controls rather
than removing any of them so this feels like randomly changing things to
work around some other problem elsewhere in the system.

What is the actual problem?  Are these different controls that are being
updated in tandem or is the control being displayed multiple times?

With these you've again not provided any analysis of the actual failure
mechanism or how your change helps so it's a bit hard to follow what you
believe your patch fixes.

I'm having a hard time parsing this but I think you're saying that the
phone input was shown as a capture source rather than a playback source?
