Comment 54 for bug 1648183

I tried to run this script (https://wiki.archlinux.org/index.php/ASUS_Zenbook_UX430/UX530#Headphones_audio_is_too_low) and it did nothing. I'm experiencing the same issue with quality headphones but it's on both channels. I created a detailed bug report here before I found this thread https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1908634 . Any advice?
