Yes, I am aware that there already exists a post with a driver for this device. I don't know what's wrong (about the driver or me) but I couldn't make it work 100%.
So I created a 'driver' myself. It is not really a driver as it's just a bunch of scripts and a few lib-like files. So here's what it does:
* preloads alsa modules required for the soundcard
(so that pulseaudio can use all 6 channels instead of stereo-mode)
* trigers some events after the device is plugged in
(launches daemons used by remote-control; restarts pulseaudio server (I'm looking forward to fix this in the future))
* completely supports remote control RM-820 (all the buttons + knob-events).
If you want to edit remote control config, take a look at the ~/.lircrc file.
I created it using ubuntu 12.04 so it should work if you're using it as well. It MAY work on some previous versions of ubuntu. I have not tested yet (and probably will not).
Hope someone will find this usefull
2) enter the directory
3) $ sh install
