emu1010k firmware does not load in 13.04 with kernel 3.8.0.
With kernel 12.10, kernel 3.5 it was working, but to make it properly load after hibernation I had to compile it into kernel with:
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="emu/emu1010b.fw emu/micro_dock.fw emu/hana.fw"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

With 3.8.0 it neither loads from the start, nor after hibernation even with above lines compiled into kernel. Log files don't show error, but repeat msg on loading firmware. Once in few seconds everything freezes momentarily. If I switch off the dock, then it does not freeze (and obviously card does not work).
If I boot into Windows and reboot into Ubuntu, card works ok (as Windows probably load firmware, I didn't switch off the external dock during reboot).

I have found somewhat similar bug in ArchLinux for kernel 3.8.6 and
related soundcard: https://bugs.archlinux.org/task/34865 , which was
said to be fixed in 3.8.8.

>From dmesg grepping on emu:
