Sound has disappeared - when I first started the sound worked - 2 days ago no sound - I’ve looked at the mixer and all that I can think of, but I’m a beginner so haven’t much clue - any help appreciated.
You could try working your way thru the openSUSE audio troubleshooting guide:
SDB:AudioTroubleshooting - openSUSE
Ensure you moved both master and PCM volume and headphone controls up in your mixer to 95% when testing sound. After you have confirmed basic sound you can move those down to a lower level to remove distortion.
To test your sound I recommend you try each of these sound tests (as both a regular user, and with root permissions) to see if one might work:
speaker-test -Dplug:front -c2 -l5 -twav
Note Linux is case sensitive, and “D” is not the same as “d”. To stop the above test, while the konsole/xterm has the mouse focus, press <CTRL><C> on the keyboard. Note you should check your mixer settings (kmix if using KDE, and alsamixer if using Gnome) to ensure that PCM and Master Volume are set around 75%. Note the test for surround sound is different.
If that test yields errors, try instead this more simple test: speaker-test -c2 -l5 -twavTry as both a regular user and with root permissions.
If you have no success with the audio troubleshooting guide, then I will need more information if I am to make a recommendation … So can you provide more very detailed information so a good recommendation can be given? In the case of openSUSE-11.1, you can do that, with your PC connected to the internet, by opening a gnome-terminal or a kde konsole and typing with root permissions twice:/usr/sbin/alsa-info.shthe first time it will update the diagnostic script, and the second time that will run the diagnostic script and post the output to a web site on the Internet. It will give you the URL of the web site. Please post that URL here. Just the URL.
If not openSUSE-11.1 you will have to use the method described in the troubleshooting guide to run the script.
Also, please to provide additional information, copy and paste the following commands one line at a time into a gnome-terminal or a konsole and post here the output: rpm -qa | grep alsa
rpm -qa | grep pulse
rpm -q libasound2
uname -a
cat /etc/modprobe.d/sound
All is well and thank you - the alsa-firmware was not installed - I have sound again - I still can’ get Kaffeine to work, I,ve installed libdvdcss from videolan and the Packman version and nothing changes - how can I know if the packages are installed?
