How do I get gnome->settings->sound to recognise my audio devices? Fedora28
How do I get gnome->settings->sound to recognise my audio devices?
I did a new fedora 28 installation recently but seem to have lost the sound. It was working with fedora26.
I've checked volume levels on the computer monitor, gnome sound configuration, and reseated the HDMI cable.
Gnome->settings->sound shows only the device Dummy Output
vlc
shows only the device Dummy Output
and does not produce audio (the video does display)
audacity
shows two devices: hdmI
and generic
. The analog generic device works. I may have other problems with the hdmi device, but would at least like to use the one that works for now.
/proc/asound/cards
shows the video chips HDMI and the motherboards analog card
0 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfef44000 irq 34
1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfef40000 irq 16
note: HDMI is the Radeon built into the AMD A6 CPU (ati driver) Generic is the Realtek ALC887-VD built into the MSI FM2-A55M-E33 mother board.
I hear nothing from: speaker-test -Dhdmi -c2
however speaker-test -Dfront:generic -c2
does produce sound
pacmd --list
shows the two sound cards
I have tried pulseaudio --kill; pulseaudio --start
The gnome->setup->sound shows only the Dummy Output device, so I'm wondering if pulseaudio is not communicating with gnome. If sound is going to the Dummy Output device and no real devices, that would explain why I hear nothing.
alsa-info.sh output is at http://www.alsa-project.org/db/?f=731...
The Live-CD exhibits the same problem - but I can't boot in the normal mode and have to use the troubleshooting mode.
I'm wondering if gnome isn't finding the pulseaudio server, or if it is more fundamental, ... or something foolish that I am doing wrong.
Can I force gnome to find the audio devices?
Install
pavucontrol
and/orpaman
and check which audio card is the default one.Thanks, I have installed them since I first idtified the problem.

It looks like I have to figure out how to get pulseaudio to recognize the cards.
pavucontrol is interesting.
for output it shows no devices available.
configuration shows two 'Built-in Audio' devices, clicking on profile offers three choices for each, But each indicated 'unpluged' I know that at least the analog device is plugged in because 'audacity' works.
