Static noise from earphones in my Ubuntu 20.04

My wired earphones are giving me static noise, I am writing this after I tried everything on this site and nothing worked. This involves:

Using the famous pulseaudio -k option ( it just transfers the sound to my PC speakers, and there is no static there, as soon I connect the earphones it starts again ).
Using echo "0" | sudo tee /sys/module/snd_hda_intel/parameters/power_save , nothing changed.
Using alsamixer, here the default volume of headphones section is full, whenever I change the master volume using the "f2" and "f3" keys the headphones section always goes very high directly as well as the PCM section, so this tool does not change anything.

So as the end option I just opened the pulseaudio logs, I used Does pulseaudio have an error log? stackoverflow post to help debug pulseaudio.

When I give the pulseaudio --verbose command, this is the output:

When I connect the earphones these extra logs appear:

When connected the noise stops but as soon as I play anything the static noise start in the background with the video sound also.

You can see in the last logs the line Freeing input 0 "Valorant: *NEW* Butterfly Knife is SO AMAZING! - Recon Skin Bundle! - YouTube" as that video is the one I am using for testing.

When I stop the video, these extra lines appear after a few seconds

I: [pulseaudio] module-suspend-on-idle.c: Sink alsa_output.pci-0000_00_1f.3.analog-stereo idle for too long, suspending ...
I: [alsa-sink-ALC3246 Analog] alsa-sink.c: Device suspended...
I: [pulseaudio] core.c: All sinks and sources are suspended, vacuuming memory

and then the static stops.

I am at a loss here on how to fix this, any pointers will be helpful thanks!
