HOW TO FIX NO SOUND on Linux Ubuntu, Debian

The first thing you need to do is check out your headphones and speakers for connection problems. It could be that some audio cable is connected to the wrong port or not connected at all.
Check the ALSA Mixer

Under the hood, PulseAudio uses the ALSA-level volume controls. If you need more fine-grained control over your ALSA-level volume, follow the steps below:

1. Open the terminal.

2. Type alsamixer and press the Enter key. You will see the following output in your terminal.

3. Select your correct sound card by pressing F6.

4. Use the left and right arrow keys to select a volume control. The currently selected item is shown in red.

5. Use the up and down arrow keys to increase and decrease volume levels for each control.

6. When a mixer control is muted, “MM” appears below the volume bar. Note that a bar can be 100% full but still be muted, so do check for this. You can unmute a control by pressing the m key. This changes “MM” to “OO.”

Thank you so much, this was quite helpful. Although in my case, the Muting was already disabled, and the S/W Swttings showed 'Hedphones', the 'Speakers' were MM (muted) in the Card Settings. That just needed to be unmuted and brought up, et voila! (I would suggest those stuck despite the video, to look at items that are Muted - marked MM, especially Speakers and/or Headphones . You may want to read the description to understand this better.)
