This happened to me today. After trying the solutions shown nothing was solved.

Install pavucontrol

sudo apt install pavucontrol

After you run the audio test with Skype Tools > Config Audio and Video (in the section Speakers).

Open "pavucontrol" and you will be able to see that Skype is trying to use a different audio output (in my case was HDMI) I changed that and Skype audio worked again.

Hope it helps.

Try uninstalling Skype and re-installing it not from Ubuntu Software. Go directly to Skype official website and downlod the .deb file. Once you have this file on your computer, open it with the "Software installation" option, by right-clicking on the icon. Install Skype from there. Once your installation is completed, go to the terminal and type:

skypeforlinux

Then you'll be able to use Skype normally.

This installation does not create an icon for you. So you have to create it.

I am having the same issue, probabaly because Skype is trying to use ALSA and ubuntu is using pulseaudio.

To clarify, there is sound (firefox, youtube, spotify, etc.). It only affects Skype.

You can try to resolve it, but I cannot guarantee anything.

One way is forcing ALSA to reload:

sudo alsa force-reload

or just reinstall everything:

sudo apt-get remove --purge alsa-base pulseaudio sudo apt-get install alsa-base pulseaudio sudo alsa force-reload

But I did not do any of those (I just hypothesize that these might help), I went for a Skype Web interface. It works perfectly in Google Chrome, so I suggest you give that a try. Unfortunately, it only works in Google Chrome, and no other web browser...

You can use:

sudo apt-get install libv4l-dev

You can check Ubuntu's sound configurations.

1. Run skype first.
2. On Linux desktop Access settings >> sound >> tab "Application".
3. Check if the 2 sound options are enabled. NOTE: My case only one option was ON so the output worked and input was mute.
4. After enabling both options to go to Skype.Good configuration
5. Access Settings >> Audio & Video >> "Make a Free test call"

Software Versions: - Ubuntu 18.04 - Skype 8.50.0.38
