Hi everyone!
I have recently started having issues with the built in touchpad and speakers / headphone jack in my asus E403-SA. They both stopped working out of the blue while i was using the laptop. They came back very briefly during a later reboot but never came back since. My basic understanding of the issue is that the elan_i2c modules fails to communicate properly with the Elan touchpad & the integrated sound card doesn't seem to be detected at all, only the HDMI audio output is detected. Here is some debug information i was able to find on the issue of the track pad:

Node 0x08 [Vendor Defined Widget] wcaps 0xf00000: MonoThe issue happens on Linux 4.10.11-1, Linux 4.10.13-1, Linux-hardened 4.11.1a-1 and Linux-mainline 4.11.0-rc8-mainline.
I tried removing the libinput config files in /var/X11/xorg.conf.d/
I tried blacklisting the hid_i2c kernel module
I checked the bios to make sure the touchpad was enabled ( even though it clearly was communicating with the linux kernel )
From what i have found, the majority of other people having similar issues fixed it by updating the kernel. Since both the sound and the touchpad stopped working at exactly the same time, I am pretty confident the issue is linked.

This was solved by passing
