SoundBlasterX Katana and PulseAudio
When you connect a Creative SoundBlasterX Katana via USB to your system, it may work right away but you soon will probably notice you cannot increase the volume to the amount you want to...
...this is due to the Katana reporting "Speakers" instead of "PCM" as volume control hence PulseAudio will not pick it up and only uses software volume control to fix this just copy the following three files to your system and trigger the necessary UDEV events.
Reload rules and trigger UDEV events
sudo udevadm control --reload-rules sudo udevadm trigger -ssound
