Hi iqbro, and welcome to the forum.

My first thought is to try this in the terminal:

Code: Select all

amixer set Headphone 75% unmute

I know it's the speakers you're trying to listen through. Some systems require the headphones to be unmuted for the speakers to work.

If that works, I can give you an edit to make to automate it so you don't have to enter that after every reboot.

If it doesn't help, we should get a look at your sound setup with this command:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

The last line of output will have a URL pointing to the info. Pasting that URL is all I need.

Hi Mr.Een

i've tried amixer set but still i could not hear sound.

here is the text from link resulted by curl..
