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?
/usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.conftweak listed in the 2nd answer to no avail. I'm assuming there's some difference between 12.04/13.04 or N76VM/ux51vz that prevents the config from working properly, but I don't know anything about alsa to know what. – David Perry Oct 04 '13 at 20:30
