# ASUS Zenbook UX390

## Volume increments don't work

Because of the "surrond sound" audio hardware on the UX390, you have to tweak a Pulse configuration file to get volume incrementing to work. Otherwise, the volume will either be full or muted, despite appearing to increment.

Edit the analog output path config and add the `Element Master` and `Element LFE` parts below.

    /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common

    [Element Master]
    switch = mute
    volume = ignore

    [Element PCM]
    switch = mute
    volume = merge
    override-map.1 = all
    override-map.2 = all-left,all-right

    [Element LFE]
    switch = mute
    volume = ignore

Then, restart PulseAudio and changing the volume should work.
