I seem to have lied.  It should be possible, and the emulator shows it
must be working well.

Do I understand correctly that the problem is that both HP and speaker
outputs are muted simultaneously when you either of "Headphone" or
"Speaker" mixer switch is muted?

If so, please give alsa-info.sh outputs at the problematic state, i.e.
the speaker gets muted by the headphone mixer switch or vice versa,
just to confirm.
