I hear this weird noise from my left headphone all the time. If I mute it from sound settings, it disappears. However, away from that, I hear that annoying sound all the time that it hurts my brains.

I searched for this problem and tried everything. Didn't fix anything.

I found this: Popping noise from laptop speakers

I tried the first one, couldn't do the second. I can't edit 

/sys/module/snd_hda_intel/parameters/power_save

I don't know why.

And then I found this question, but I don't have a line like: 

options snd-hda-intel power_save=10 power_save_controller=N

I also have this error if it matters:

enter image description here Thank you very much.

Quoting a suggestion...

Your DDX does not work with your current kernel and/or libdrm. There are at least three possible reasons for this: the nouveau DRM kernel module is not loaded, a version mismatch between the Nouveau DRM and libdrm, or KMS being disabled.

First check, that lsmod command lists nouveau. If not, do modprobe nouveau to load the nouveau DRM kernel module, and check the kernel log for possible errors.

If the kernel module nouveau is loaded according to lsmod command, but there are no kernel messages about nouveau at all, then most likely Nouveau KMS is disabled. This prevents the driver to work at all. Possible places to disable KMS are:

kernel command line with: nomodeset, drm.modeset=0, nouveau.modeset=0 or similar modprobe.conf or modprobe.d/ adding the module options drm modeset=0 or nouveau modeset=0 initramfs carrying the above module options Check and remove all those that you may find, and retry.
