Comment 23 for bug 535476

The problem of stereo with this device is due to the configuration of the .asoundrc file, When I connected this device in my LinuxMint 16 it detected it as a stereo device, but later applied the configuration recommended at http://www.6by9.net/output-to-multiple-audio-devices-with-alsa/

it started to work as a 5.1 device... if you kill pulseaudio and just let ALSA, you will know it's ALSA who is not working as a 5.1 but detecting it's 5.1, alsamixer...
