Soundcard detected, but no sound, maybe it is just because of mute setting

If this topic is in the wrong place, please move it to the right place.

My PC is old, it is LGA 775 mainboard. When installing Ubuntu MATE 22-04, it's don't have sound came out to my speakers. I have been trying many different profile for sound setting from Menu > Preferences > Sound in Hardware section and got no luck.

Then i run MATE terminal , type alsamixer and displayed like this:

look like Front is muted.
to unmute, use left/right arrow to select Front and then press M

But, this is anoyning because everytime Ubuntu start, Front became muted again and i must manually switch to unmute. To workarround this problem i create:

amixer -c 0 set Front unmute

make startup item from Menu > Preferences > Startup Applications then Add.
in Command section, write code above.

NOTE: different soundcard has different name for audio output, for example, maybe it has name Speaker or other name, so the command become:

amixer -c 0 set Speaker unmute
