Title:
sound not working in 4.15.0-58, but does in 4.15.0-55
Status in linux package in Ubuntu:
Confirmed
Bug description:
First excuse me, this is my very first bug report, if anything is
missing, notify me on email.
----------
I find it rather hard to believe, but since I installed kernel:
> 4.15.0-**58**
several days ago, my sound on Linux Mint 19.2 Cinnamon stopped
working, and no matter what I tried like:
sudo apt reinstall alsa-base pulseaudio
sudo alsa force-reload
+
reboot(-s)
+
alsamixer
nothing brought me sound back, so I just installed an older kernel,
namely the littlest bit older one:
> 4.15.0-**55**
now everything works like a charm.
-------
How can I debug this and figure out if the problem is a bug in the
kernel itself or in some other audio-related package? I don't know
what exact information you could require for this.
-------
I have just reproduced the problem by upgrading back to 4.15.0-**58**
from 4.15.0-**55**. Sound not working again. Plus, by switching to an
older kernel proves sound is functional.
-------
Hardware:
laptop Dell HG6D142: [direct link to product page][1]
----------
$ lsb_release -rd
Description: Linux Mint 19.2 Tina
Release: 19.2
-----------
expectation: sound working
-------
happened: sound does not work at all, neither with Intel GPU, nor
Nvidia GPU online, tried all I could mentioned above
--------
I attach a simple diff between 55 and 58 loaded.
-------
Thank you!
