To try to rectify this issue I did the following:
Uninstalled and reinstalled Gnome via the dnf group
Did a dnf groupupdate on all groups that looked like they had
something to do with audio/videos for Gnome and KDE, except the
multimedia group because of conflicts with one installed package
which can't be removed because a protected package had a dependency
on the package in question.
I uninstalled and re-installed pulseaudio.
Used dnfdragora to install all packages that looked like they
had something to do with codecs and audio/video libraries.
Then when I had finished that I tried loading some youtube
videos into Firefox Nightly and those videos played without disabling
the audio but they did not produce any audio.
I shutdown last night and when I started up this morning I again
tried to play the same youtube videos in Firefox Nightly and it is
back to the original state of not playing the videos unless audio is
disabled in the video.
Now that there is an audio interface in KDE System Settings that
seems to be interfacing to pulseaudio, and when I try to test the
sound from the stereo speakers for my headphones I get the message
"Error trying to play a test sound. The system said: 'Invalid state'".
The pulseaudio manager seems to be indicating that pulseaudio is
using alsa backend modules to connect to the playback devices, also
switching devices doesn't make any difference to the issue.
I also tried issuing the command sudo systemctl
is-system-running and that returned the response "degraded".
How do I determine what is causing the current state?
I don't have an answer, since I haven't had an issue like this. I
wonder if you somehow got pipewire installed as a dependency, as it is
the default in f37. If you did, pulseaudio and pipewire will be stepping
on each others toes, because they are both trying to control the same
devices via alsa.
rpm -q pipewire
Pipewire is installed but it seems to me that it was not handling
devices properly as I had the audio issue before I did the pulse audio
install/reinstall, unless pulseaudio was also installed as part of the
F37 install from scratch when I did my hardware upgrades.
Is there anything in journalctl when this happens?
journalctl -r
There is this message from journalctl -r, and there are lots of these
when I try to play the video with audio unmuted:
Dec 01 08:50:08 fedora pulseaudio[2638]: Failed to create sink input:
sink is suspended.
Have you looked at the pavucontrol output when you are trying to do
this? What is the default device set in pavucontrol? Does it show
audio playing even though there is no sound?
I've looked at pavucontrol and there was no indication of any audio
while the video was attempting to be played. I did try to change the
configuration of my headset device to Digital Surround 5.1 and that just
produced static in my headset even though the headset is supposed to be
5.1 Surround, but when I changed it back to the Analog stereo setting
the video started playing with audio output, and if I changed the
configuration to Digital Stereo the video continued to play with audio
without interruption. The other thing that was noticeable with this is
if in pavucontrol I changed the firefox output to either of the other
two devices that are shown, being my monitor and my external 5.1
surround speakers which are switched off, the video playing went back to
the original state of only playing properly if the audio was muted.
I'll continue to monitor this and see how it goes and if it continues to
work then I might uninstall pipewire as that seems to not work properly
on my system.
regards,
Steve
Have you tried using alsamixer to look at the settings for the
default device? You will have to specify the card in order to get the
actual configuration of alsa, since pulseaudio has captured it.
Something like
alsamixer -c3
where 3 is the card number that is shown for the default device from
aplay -l
Your number will probably be 0 or 1.
