Bounty: 50

I have a Dell xps13 that previously had 14.04 and the sound worked fine. I recently installed 18.04 and now I have no sound through either my speakers or headphones. The sound settings look like this:
enter image description here
(Note that there is no ‘Test Sound’ button. )

I’m following the Ubuntu troubleshooting guide for sound.

At step 3, entering wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh yields the output: https://pastebin.com/raw/44UDnp63

Running the code in step 4 yields https://pastebin.com/raw/YinifjQC

I’ve tried reinstalling alsa and pulseaudio.

I’ve checked with pavucontrol to make sure that nothing is muted. This is what the panel looks like:

(The lower bar indicates that sound is playing, but I don’t hear anything out of the speakers/headphones.)

Please help!
