Comment(by lennart):

 To my knowledge HDMI has now fixed channel mapping, so some negotiation of
 channel mapping needs to take place, and I don't see how ALSA would
 support that.

 In PA 0.9.16 it is very easy to extend the list of know mappings, by
 editing /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf. So if
 there is a an ALSA device string which has a known channel mapping it is
 very easy to add it to the list of profiles PA can probe for.

 In older versions you can still use module-sink directly and use
 channel_map to define the channel mapping manually.
