Notification area audio widget suddenly invisible on Fedora LXDE spin

[Someone]

My sound abruptly stopped working, and the notification area widget
stopped appearing. It hasn't been working for a couple of weeks, at this
point, though it had been working fine before that. (Before it stopped
working, the notification area widget had been displaying, as well.

I can run pavucontrol manually, and the only output device that is shown
in the relevant tab is "Dummy Output".

I really wish I could listen to music, but neither my laptop's built in
speakers, nor the stereo system plugged into the side audio jack work at
all.

As per the wiki sound troubleshooting page, I removed the
alsa-plugins-pulseaudio package, but that, alas, that didn't help, either.

Any suggestions would be appreciated.

Thanks.

It has to do with your engagement, not with the language per se, dear

If you use the PulseAudio sound server, it is one way to test it.

Enlighten yourself with
man 1 paplay

That specific live image probably has relatively outdated version of the
kernel.
Does this help us in finding solution?

I can not answer that question.

Are you eager to test the audio device with the latest available rawhide
nodebug kernel, on your own responsibility?

BTW what is the output of the following command:
uname -a

Hi poma,

I don't mean to be rude, but is English not your first language? It
would help me a lot if you could annotate your commands and codes more
with some explanatory prose. For example, I couldn't really figure out
what you meant by...

    $ paplay

...at first, since I just ran it and it said "Failed to open audio
file." Then I realized that it's probably some sort of substitute for
"aplay", and ran it with the wav file as its argument.

In any case, I have no idea whether you expected it to work as opposed
to the "aplay" version, but it didn't.

Also, I'm not sure what you meant by linking me to the youtube video,
but the image I booted from when my audio worked was this one:
http://download.fedoraproject.org/pub/fedora/linux/releases/20/Live/x86_6...


I don't know the first thing about upgrading or changing kernels, or
installing new versions like rawhide. Would I lose all my installed
applications and user data?

Is there any way to upgrade without having to make a new live usb
installer stick, some on-line method of upgrading?

Thanks

Fedora Live, this one? :)
http://www.youtube.com/watch?v=pbm_VfA7Qps

Strive to a newer kernel version.
http://dl.fedoraproject.org/pub/alt/nightly-composes/
e.g.
http://kojipkgs.fedoraproject.org/work/tasks/7005/6747005/

Or just pick up the kernel,

Still no luck :(

FWIW, I just tried booting from the Fedora Live USB stick I'd used to
install my system, and "aplay /usr/share/sounds/osmo/alarm.wav" worked
from the speakers. Would it make any sense to look at the configuration
in that environment and try to borrow values from it?

HD Audio models:
https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt

$ modinfo snd-hda-intel | grep model

1. Create a file as root:
/etc/modprobe.d/snd-hda-intel.conf

2. Type in the following single line:
options snd-hda-intel model=auto

3. Reboot

~~~~~~~~~

2a. Eventually change the "model" parameter(HD-Audio-Models.txt) until
the card starts to work, e.g.
options snd-hda-intel model=thinkpad
..
options snd-hda-intel model=laptop
..
etc.

3a. Reboot after each change.

This can be done faster, but do it with rebooting.

Hi poma,

I assume that I'm meant to run those commands? Or are they just a list
of various commands that I might find useful to explore? In any case, I
ran them all in order, though many of the ones prefixed with "$" failed
without root, so I ended up running them all in order again as root.

Here's the transcript of my shell session, although my sound still
doesn't work: https://dpaste.de/4KuR

In the latter case, I'm sorry, but I'm afraid that all this stuff is way
over my head. I've tried reading some of the output and I don't even
know where to begin in trying to decipher it..

Thanks

FWIW, I've just reinstalled alsa-plugins-pulseaudio and rebooted. While
the widget seems to be here to stay, the only channel remains "Dummy
Output", and sound still doesn't play.

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 03)

Does that help?

I was able to figure out that the program responsible for the
notification area audio widget is PNMixer, and I was able to get it back
by running:

    pnmixer

Unfortunately, however, it's only the icon, and my sound hasn't returned
with it. :(

What is your make/model laptop?

Not familiar with laptops....but I suppose their audio device still sits on the PCI
bus....  What does....

lspci | grep -i audio

show?

My kernel got upgraded along with everything else in a run of "sudo yum

Thanks for your tips.
