No sound from laptop's speakers

Hello. I’m trying to get sound working on this Asus laptop following some of the threads here on the forum, and so far I’ve been out of luck. The headphone jack and internal mic are both working. Everything is up to date.

Hello,

Switch to another kernel. That one is EOL.

ok, I have installed and booted
5.9.1-1-rt19-MANJARO
Situation is still the same regarding the sound.

See this bug report and see if it helps https://bugzilla.kernel.org/show_bug.cgi?id=206589

Are you dual booting with Windows? Disable fast boot from it.

Other Asus models with the same Audio card seem to have some solutions

A post was split to a new topic: Llenovo G51 sound question

I am indeed dual booting with Win, and I’ve disabled fast boot but no change. I’d like to mention that I’ve had Manjaro as the single OS and there still wasn’t any sound from the speakers. Both OS’ are setup on different drives. Manjaro was first, and when I installed Windows I physically removed the Manjaro drive.
I am now trying the solutions from the links, hopefully I’ll get somewhere.
1st link: crated the file alc294-sound-patch.fw and pasted content, added option in alsa-base.conf, rebooted, still no sound. I’ve undone it and rebooted again.
2nd link: booted into Win and shut down while pressing shift, booted back into Manjaro, did sudo alsactl init, still no sound
3rd link: kind of similar to the 2nd, but I won’t remove the sound drivers from Win since I’ve already had Manjaro as the only OS
4th link: tried hdajackretasking , mapped the internal speaker to the headphone jack. still no sound.
I’ve checked alsamixer periodically to make sure nothing is muted.

Also http://alsa-project.org/db/?f=b2ebb761eea340b04b0777156b43a393922f0488

I’ve found a semi-solution, however the speaker’s volume can only be changed by adjusting PCM in alsamixer. Changing master volume does nothing for the speakers, only mute them if it’s 0.
in

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

add line and reboot.
