I'm currently experimenting with different ways to make the system autodetect if surround2.1 is available through a four channel setup (e g laptop surround speaker) and fallback to 5.1 if it isn't.
It's a bit tricky, especially given that the LFE speaker could be on left channel, right channel, and both, so meanwhile, this fallback should be better than nothing and help establish a standard for upper parts of the stack (i e PulseAudio).
Thanks, applied both patches.
