How do I get sounds to work on my PC

To start off with, you need to be a bit more specific. There may be several reasons for no sound.

1. Do you have a functional sound card and speakers installed? If yes, then:
2. Do you have the drivers for your sound loaded? If yes, then:
3. Is ALSA running?
4. Are the volume controls on your sound applet turned up?
5. What DE/distro are you using?

Please paste the output from these commands and use code tags so that it's easier to read.

Open up your almixer and make sure that all of the buttons are raised up all the way.

I had to add myself to the audio group log out and log back in again.
If you still don't have sound after that open a terminal and type
And hit ENTER. After that the alasamixer will open with a dark background and you'll see all of the columns.
When I did it I went thru each column muted and than unmuted each column and raised each one up; the master, the PCM, the mic and etc.

After that I pressed the ESC key and saw the orginal command I put in the terminal. Just close the terminal and you should have sound.
