Thanks for the log. Looking at the log, PulseAudio seems to do the right
thing. It first tests input:multichannel, which succeeds, then
output:multichannel, which also succeeds, but when then trying full
duplex, we get an error back from the kernel:

I: [lt-pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_PREPARE failed (-16)
I: [lt-pulseaudio] alsa-util.c: snd_pcm_hw_params failed: Device or resource busy

As a result, "Multichannel input" and "Multichannel output" are
available, but not the combination of both. From your point 4) it sounds
like the gnome audio settings react a bit strange/buggy on this. I
assume you have checked both "output" and "input" tabs, right? If you
change from "Multichannel output" to "Multichannel input" and it
disappears on the output tab, it should start showing up on the input
tab instead. Otherwise you can use the pavucontrol to change profile (on
the configuration tab of pavucontrol).

But the main question is why full duplex fails here - are you getting
full duplex to work with other applications (that are not using
PulseAudio)?
