Does your kernel support hotplug firmware loader (CONFIG_FW_LOADER)?
And is hotplug working?

Check whether /proc/asound/devices whether you have a "[1-0] hardware
dependent device".  If you have it, the hotplug firmware loader isn't
enabled.  Use vxloader, run "vxloader -c1".

With the attached patch, you can check whether the firmware is loaded
or not via the proc file.
