#cat /etc/asound.conf

    pcm.!default {
        type hw
        card 1
    }

    ctl.!default {
        type hw
        card 1
    }

After reboot also no sound

Re: Sound not working

Overriding the asound.conf that way disables all automatic transforms that would be happening. To properly check whether the speakers work you'd do a

speaker-test -Dhw:1,0 -c2

if that does work then the speakers do generally work and you should adjust that asound.conf to use

defaults.pcm.!card "PCH"
defaults.ctl.!card "PCH"

which will retain dmix and multi-application audio guarantees.

Re: Sound not working

Changing

#/etc/asound.conf

defaults.pcm.!card "PCH"
defaults.ctl.!card "PCH"

content worked !!

Re: Sound not working

Great, please mark as [SOLVED] by editing the title in your first post.

Note that should you ever want to switch from plain ALSA/dmix to something like pipewire/pulseaudio you should remove this config and use pipewire- or pulseaudio-alsa respectively.
