I'm going to assume that "the problem" is that you have no sound. If the problem is more specific than that then let me know. I'm also assuming that you are using MATE, the default Trisquel desktop environment, and that you have not uninstalled Pulseaudio or installed JACK. Let me know if any of these assumptions is incorrect. Here are some things to try: First run $ aplay -l $ arecord -l $ lspci | grep Audio $ sudo lshw | grep -A 5 multimedia and copy/paste the output of those four commands here. Next, go to Control Center -> Sound, and go to the "Hardware" tab. You should see at least one sound device. For each device you see, click "Test Speakers" and test all of the output channels. If you are using a laptop, try this both with and without headphones. See which devices can and cannot produce sound. Next, start playing some music or something through vlc or mpv (not Abrowser) and while that's going run $ alsamixer (You might have to install it first.) alsamixer exposes lower-level settings for your sound cards than MATE's volume preferences. Here are the basic controls - Left/Right to switch between faders - Up/Down to adjust a fader - M to mute/unmute a fader - F6 to switch sound cards Unmute and turn up every fader for every sound card until you get sound or run out of faders to try. Report back the results of trying these things. The more detailed you can be the better. Hopefully that will give us some clues as to what the problem is.
