Well, this is one of my looong-standing TODOs. Originally I wanted to implement a new API to get/set the channel-mapping, mainly for HDMI. But, I've been recently too busy for other tasks (I can spend little time for ALSA), thus it's pending forever.
You would only need an API to get the channel mapping. The HDMI sink will report its speaker configuration through a CEA code (section 7.4 of the spec), and if we parsed the EDID info we could present the relevant channel order to user-space apps.
