I'm getting no sound (dummy sound) from speakers on my freshly installed Mint Mate. I looked up and applied most popular solutions found online, but could not get it to work. Drivers are up-to-date, when looking into system mixer, the volume seems to be displayed, but still no sound. In amixer, all values are set to '0', yet no sound (see below). I also tried unmuting via command line, but no luck. I'm currently unable to plug in any headphones into the port, so can't tell if it works.
on forums.linuxmint.com I found a couple of related posts, and one user popped out: MrEen. He has a lot of knowledge on the issue of missing sound, that he compiled into a set of Fix Tips. However, nothing from that list seemed to be a solution to my problem, so I asked him personally, and that's the thread.
I know that Cinnamon is the trendy choice for desktop environment with Linux Mint, but ever since an unfortunate misadventure with video drivers I have been using the somewhat more stable and somewhat faster MATE (pronounced Ma-Tay, per their home page) environment. Overall I am very happy with it. There are, however, occasional hiccups with the panel, the bar along one edge of the display (bottom in my case) containing launchers, tabs for open applications and general what-not. Occasionally, for reasons beyond me ken, some of the icons will be screwed up, duplicated, or duplicated and screwed-up. This morning, for instance, I found not one but three iterations of the audio output icon (looks like a loud speaker, used to set audio preferences). The first icon had the normal appearance, meaning audio was enabled, while the second and third were indicating that audio was muted. (Despite the 2-1 vote against, audio was in fact enabled.)
Glitches like that do not render the system unusable, but they are annoying. So I dug around a bit and discovered that the system command mate-panel. Run from a shell script or a launcher, the command mate-panel --replace seems to do the trick of restarting the panel (and hopefully fixing the glitch that made you restart it). If you run the command from a terminal, be sure to push it to the background using an ampersand (mate-panel --replace &). Otherwise, it will tie up the terminal session, and when you break out of it (probably via Ctrl-C) the panel will rather unhelpfully evaporate.

The tool has a built-in timer that automates audio recording on given clock time or after time period, auto stop when the recorded file size exceeds a limit. And, it can be controlled via Rhythmbox, VLC, Audacious and other MPRIS2 compatible players. For Skype users, it can automatically record all your Skype calls without any user interaction.
The thing about PulseAudio is that (at least in my experience) it gives you all these awesome features, but for some reason, it has never worked that well for me. But ALSA, on the other hand, has always been an extremely stable one and has worked on all of my audio hardware devices.
In the past, I used to use the PulseAudio Configuration window to disable this audio amplification, but in Ubuntu, Pulse just automatically enables this audio amplification. So most of the time, I end up with no sound outputs.
5. As said before, for various reasons, I have to disable the audio amplification; otherwise, the audio is muted. So if you too not getting any audio outputs after running Totem, for instance, then simply open your Terminal window and enter the below command.
Thank you very much! I got help from dynobot computer audio on installing mpd but the piano music with sonata client was distorted. So annoying because I know what a piano is supposed to sound like. Then I followed your instructions: and wow! distortion gone and just beautiful music. Thank you again.
I so love linux.
