Did these enums have different names in earlier versions, or did support for them just not exist?

[barracuda156]

@kcat Looks like they exist only in recent versions:

10.15+: https://developer.apple.com/documentation/coreaudiotypes/kaudiochannellabel_righttoprear
13+: https://developer.apple.com/documentation/coreaudiotypes/kaudiochannellabel_rightsidesurround

Not 100% sure, but I do not think there are older names for them. Likely we either need not to use them or provide definitions.
