Dummy output on a Dell XPS laptop running Ubuntu 24.04

Question

I am running Ubuntu 24.04 and have a Dell XPS laptop. My speakers only show Dummy Output, and there is no sound. How do I fix this?

Answer 1

I am have this problem in Ubuntu 24.04.1 on a Dell Precision. I have Dummy output as Sound Output Device:

❯ aplay -l
**** List of PLAYBACK Hardware Devices ****

What works for me every time is to run alsa force-reload twice. I don't know why running this command only once doesn't work, but after running the second time it works.

To fix try this:

sudo alsa force-reload
sudo alsa force-reload
aplay -l
