--> There are two ways of making it work: #1 a. Add to rc.local : echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs echo 1 > /sys/class/sound/hwC0D0/reconfig b. Add options snd-hda-intel model=asus-mode4 in /etc/modprobe.d/alsa-base.conf c. Reboot d. Set the mode to "Analog Stereo Output" and then to "Analog Surround 5.1 output" in the sound settings panel.
