Lost sound on Omen laptop

Hello. I seem to have lost all sound output devices recently. Sound Output device only has one option: Dummy Output. The internal speakers nor the headphone jack has sound. I also tried to hook it up to a bluetooth speaker but it won’t connect. All these were working a few days ago.

Troubleshooting steps I took:
I have tried to change kernels but without a resolution. On stock now. Please note that if I hook up an HDMI cable to a monitor, that shows up as an output device. However, the monitor doesn’t have speakers. I have 2 users set up and both are affected.
Also, based on another thread I installed sof-firmware but there wasn’t a change.

Well, I seemed to have stumbled upon an answer, a command, whereby it would reinstall everything:

pacman -Qqn | pacman -S -

The sound seems to be back now and the devices (headphones and speakers) are back in the sound panel. Bluetooth speaker had to be re-paired.

Kernel v5.13 is no longer supported on Manjaro
Kernel v5.14 has been marked End Of Life in update announcements and not be supported by Manjaro soon

I suggest you install kernel v5.15 using Manjaro Settings Manager GUI
( manjaro-settings-manager -m msm_kernel )

OR use these terminal commands to install new kernel and remove old one

sudo mhwd-kernel --install linux515
sudo mhwd-kernel --remove linux513

Later kernel may have better support for audio device Intel Comet Lake PCH cAVS (Realtek ALC295)
