Recently I needed advanced sound hardware for my computer. Dolby® Surround 5.1 support was a must, several input and output options as well. Then I came across Sandberg USB Sound Box 7.1 which appeared to be a reasonable choice. Sadly, manufacturer does not officially support Linux, however, here is my quick guide to make it work nice and smooth.
First of all, about the device:

- USB HID class spec.1.1 compliant

- 1 x S/PDIF Toslink optical digital output
- 1 Sandberg USB Sound Box 7.1

About Linux compatibility from Sandberg FAQ:
Will this product run on Linux?
Yes, but the software provided is not supported by Linux. You can use software such as Alsa and Pulse Audio instead. Please note, however, that Sandberg does not support Linux.
What a shame. Whole setup is piece of cake on my favourite Linux Mint. Let’s get started.
Connect your surround sound card to computer via USB interface, wait a few seconds while it tries to identify device and then hook it up to your surround system. Connection diagram is provided in official user manual, so I’m not going to cover this.
Open Software Manager and search for „pulseaudio“ or use nice Terminal to install it by command:
sudo apt-get install pavucontrol
Which is actually something Sandberg advise on their FAQ. Next, having PulseAudio doesn’t mean your device starts working automagically – you need to set modes. Go ahead and open on your Cinnamon menu Sound & Video > PulseAudio Volume Control and pick values as shown:
Now, native Linux Mint sound settings (menu > Preferences > Sound) should start showing „CM106 Like Sound Device Analog Surround 5.1“ (same you’ve set in PulseAudio config):
When you click „Test Sound“, you should see following window which on certain clicks will make your surround system talk:
All done, enjoy movies in Dolby® Surround 😉
