Pulseaudio explicitly disables dmix when opening ALSA devices. The only
way to get pulseaudio to ever use dmix is to manually force it to by
using a non-standard configuration. I don’t see any reason to explicitly
document this one unusable configuration (of possibly many).

lib32asound2 is not within my control. Please file a bug there.

Great! So why are you re-opening this one then?
