no sound from my linux system

Some information would be useful.

What distro/version do you have installed, what desktop environment are you running, what is the make/model of the computer, and what is the sound card? (You can answer the last question by running the command lspci in a terminal; depending on the distro, you many need to be root to do so.)

Hi...

Welcome to the forum

Per frankbell's instructions above, the following command might make the information from lspci more concise...

Just as some helpful advice, please never post without sharing the necessary information about your system first. It helps us help you a lot quicker.

Write out complete sentences please.

When I was running Ubuntu I found out that the sound was muted by default.
Same thing happen to me after a fresh install of Debian.

-:Try raising all of the columns (master and pcm etc.)all the way up in the Alsamixer.
Exit after making changes.
[mm] means that the column is muted and [oo] means that the column is not muted.-:-

To do so; open the konsole/terminal and type:
- aplay -l will tell you what sound card you have.

The first step is to run the volume control from the menu and make sure the sound isn't set to 0: it sounds silly, but it does happen.

The next is to consider whether you may have more than one device. Every motherboard has a sound chip, some video cards have one, some of us use USB speakers or headphones. The command "aplay -l" will list devices. If you see more than one (card 0, card 1, etc), then you need to make sure Linux is using the right one. Try running pavucontrol in a terminal: if you haven't got it, then install it with "sudo apt-get install pavucontrol. That will let you set the devices and basic volume for both input and output.
