This is a new issue I’ve had for about two weeks now. I had debian 12 and everything was working fine. One day, opened laptop, no sound. Upgraded to debian 13, same issue. Switched to Fedora 42 out of preference, same issue.

Bluetooth is fine, HDMI audio is fine. No audio from speakers, settings shows Dummy Output as the inactive card.

This is all the information I know to provide, please let me know of any additional information from my setup/device you may need to help fix this problem.

Thank you,

You did not say if you may be dual booting and if so, do the speakers work in the other OS?

The sudden change sounds almost as if there may be one of 2 causes.

An update may have changed the driver and the chipset may no longer function due to the changes.
or
A hardware failure may have occurred.

Additional info that may assist would be to post the output of inxi -Axx so we might see the actual chipset used and the driver.

I do not dual boot, I only use Fedora.

This Dell Latitude laptop has the same chip. Sound is working with the 6.16.9 kernel. When reporting issues please install current Fedora and vendor firmware updates so you aren’t chasing a solved issue. If updating doesn’t get audio working, use journalctl to look for relevant journal entries. Here:
