Hm, then maybe the effect of removing noise appears no matter which input of NID 0x0b be unmuted?
I've retested some, and you're right, it seems some others do make the noise disappear:
For example, this works too:

Other pairs do not work, but some do change the noise sound.
So; if everything is muted, it causes some codec bug to appear. If this only happens in the speaker, maybe we should try to reroute the speaker to go 0x02 -> 0x0c -> 0x14 instead of 0x03 -> 0x0d -> 0x14? What will happen if you change 0x14 to take its input from 0x0c instead?
