Perhaps unrelated, but AFAIK Pulseaudio installs its own versions
of some ALSA files. These can cause some multi-channel interfaces to only
show as having two channels (and not necessarily the ones you might
expect). I know some users of M-Audio ICE1712 based cards have encountered
this for example.

If you've removed Pulseaudio it might be a good idea to make sure it hasn't
left behind any modified ALSA configuration files.
