Roccat Kave Drivers
DriverAssist performs an in-depth scan of your entire system and all devices attached to it and verifies that you have the latest and most compatible drivers installed. It determines which drivers are missing, corrupt or obsolete. After the initial scan, DriverAssist matches your device with the latest and most up to date version of your drivers by scanning its 26 million drivers database. Before DriverAssist installs the new drivers, it performs a backup of your actual drivers just in case the new drivers would turn out to be incompatible with your system or device. This is an added security for your computer. Lastly, DriverAssist downloads all the files required and installs the drivers for you. Your drivers are now up to date and your device should now be working exactly as it should.

Roccat Kave XTD doesn't work properly out of the box. Roccat support team advised to edit /etc/pulse/daemon.conf: The Kave XTD 5.1 is officially not designed to be compatible with Linux but we were able to use the Kave XTD under Ubuntu 12.04.3 LTS (3.5.0-40-generic) without a configuration software, all we had to do was to edit the pulse daemon.conf at /etc/pulse/daemon.conf and add this line: default-sample-channels = 6 Your system should detect the USB 5.1 soundcard which is built into the KaveXTD just fine.
So it should work as 5.1 Headset. We were however unable to use neither the pulseaudio-tool nor alsa's speaker-test to test the channels but almighty VLC played the Dolby Test Video ( ) just fine with all channels enabled and controllable through the XTD's volume control unit - which should verify that all channels are properly processed by the soundcard. Please understand that we cannot guarantee you it will work out of the box on your machine with your kernel, you should be prepared to do some trial-and-error config-hacking.

Roccat Kave Microphone Not Working
You might want to run Kmix to check that no channel is muted by accident. However it doesn't work on Ubuntu 14.04 (at least for me). I had distorted sound and subwoofer didn't work at all. So I googled a little bit and found working solution not just for Roccat Kave XTD, but for most external usb sound cards: pacmd list-cards set-card-profile 1 output:analog-surround-51.
