Description leonardogilrojo 2023-04-11 04:46:12 UTC 
SUMMARY
After a recent update, the sound completely stops working. With the help of a user here: https://unix.stackexchange.com/questions/742445/audio-stopped-working-after-a-system-update/742530#742530, 
we narrowed it down to a problem with the ALSA drivers on the Linux kernel.

The problematic kernel number is 5.19.0-38, and downgrading to 5.15.0-69 fixes the problem. 

Here's the output of aplay -l:

I think I have a similar issue with kernel 6.2.0-26-generic.

In the process of trying to fix it, I seem to have lost all of the audio devices in the control application, but they still show up in aplay -l

Is there a work around for this?

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
