gives a solutiion (see all messages).
gives the cause:
PA knows no suitable default channel map for devices that have 10
channels (in contrast to 1, 2, 4, 5, 6, 8). ALSA doesn't know either,
and we default to the ALSA channel maps.
I am not really sure what I should be doing in this case.
Does you device have any implicit channel mapping that we could adopt?

Comment: Seems like this is just a pain old "distro" bug. If the ICE 1712/24 gets supported by the "kernel", the distro needs to carry whatever additional configuration files needed to give all it's channels proper ALSA names and the same for pulseaudio. So if kernel/sound/pci/ice1712/snd-ice1712.ko and kernel/sound/pci/ice1712/snd-ice1724.ko ship with a distro, additional ALSA and Pulse config files for them should ship with the distro as well.

PS: I haven't tried reinstalling pulseaudio to find out if this is still an issue in Fedora . Maybe it's already fixed?
