Asus Rog G551VW | Noise | Headphones | Suspend

I am having an annoying problem on my laptop Asus Rog G551VW.
I have noise starts when I use my headphones.
My laptop has one input for both sound and microphone.

I spent the last two days to find a proper solution.
It’s sensible to mention that I faced this problem across the most famous distros.

Let me list all solutions that I tried recently, whereas I should mention that on a fresh installation the noise in the headphones doesn’t disappear at all whether in reboot or suspend.

Solution #1 (pop_os 21.04/ manjaro 21.1.6 lts-kernel)


options snd-hda-intel model= alc668-headset enable=1 index=0
/etc/modprobe.d/alsa-base.conf and reboot.

1- No noise sound on startup.
2- The noise return when suspending, to solve the problem I must reboot/shutdown.

Solution #2 (pop_os 21.04/ manjaro 21.1.6 lts-kernel)


options snd-hda-intel model=alc668-headset enable=1 index=0
options snd-hda-intel power_save=0

/etc/modprobe.d/alsa-base.conf and reboot

cat /sys/module/snd_hda_intel/parameters/power_save => 0

1- No noise sound on startup.
2- The noise return when suspending, to solve the problem I must reboot/shutdown.

Solution #3 (pop_os 21.04/ manjaro 21.1.6 lts-kernel)


options snd-hda-intel model=alc668-headset enable=1 index=0

/etc/modprobe.d/alsa-base.conf and reboot

Set laptop to suspend

sudo alsa force-reload
pulseaudio -k

1- No noise sound on startup.
2-The noise return when suspend. When run sudo alsa force-reload the noise disappear, maybe you need to run that command many time.
3- This solution does not work on manjaro, when you run it "sudo: alsa: command not found".

So, I think the problem is because of ALSA. The solution #3 works but on arch-based distros the command sudo alsa force-reload does not work at all.
