I recently purchased an Asus Zenbook UX51VZ and installed Kubuntu 13.04 x64 (all defaults still) on it and most things seem to work fine, with just a few exceptions.
adding options snd-hda-intel model=asus-mode4 to /etc/modprobe.d/alsa-base.conf as suggested in this post has enabled additional audio options, but a 2.1 profile is not among them. The external subwoofer appears to be on the back right channel in a 4.0 surround sound setup - how do I create a 2.1 profile that correctly maps that channel to the subwoofer?
