Invoking hdsploader does nothing with the driver with hotplug-fw
loader support.  It's simply ignored.

Did you get any kernel messages after loading snd-hdsp?

Anyway, please check the following:

- Whether your kernel supports CONFIG_FW_LOADER.
  See /proc/config.gz (if any) or /usr/src/linux/.config file.

- If fw-loader is supported, the firmware files must be installed
  properly.  Check /usr/lib/hotplug/firmware directory whether
  multiface*.bin files exist.

- Remove install in /etc/modprobe.conf to be sure.

If they are OK and the system still doesn't work, something wrong in
the driver or in the hotplug.


As a last resort, you can disable the fw-loader support in hdsp
driver.  Remove the check in alsa-driver/pci/rme9652/hdsp.c

	#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,0)

so that the following is enabled always.

	#define HDSP_USE_HWDEP_LOADER

(don't forget to remove the corresponding #endif, too)
