The peripheral is advertized as Headphone/Earphone, and seems like Microphone is not in the spec list. Still the ChromeOS boards see microphone and offer it as input channel.

They probably make a version with a mic and are too lazy to ship two firmware versions. We can add a quirk for it in the kernel. Or if that isn't possible blacklist it from userspace.
