oK, so I understand no sound in any application.
Please note that in a forum such as openSUSE forums, there are typically ‘stickie’s’ at the top of each forum subsection, providing suggestions to users. 5-years ago I wrote this stickie: https://forums.opensuse.org/english/get-technical-help-here/multimedia/309430-welcome-multimedia-sub-area.html … its still in place and I think it is mostly still valid.
Please, can you do a simple test for your sound ?
A simple test to see if your sound works, is to open a konsole or xterm, and type or copy-paste:
speaker-test -Dplug:front -c2 -l5 -twav
Note that Linux is case sensitive, and “D” is not the same as “d”. While the konsole/xterm has mouse focus, hit CTRL-C to stop the test. Note that you should check your mixer settings (alsamixer in the terminal, though graphical programs like kmix may also be used) to ensure that PCM and Master Volume are not muted. If need be, raise the sound levels and retry until you hear sound. Note that the test for surround sound is different.
If that test yields errors, try instead this more simple test:
speaker-test -c2 -l5 -twav
If there is no sound from either test when using a konsole (or xterm) as a regular user, try as user root, i.e. type su and then try the test line. If you get sound with root permissions, but you got no sound as a regular user, then you probably have a permissions problem. In that case, let us know as there is a fix we can pass for that.
If no sound from any of the above, then please, per the stickie,
and select the SHARE/UPLOAD option and after the script finishes it will give you a URL to pass to the support personnel. Please post here the output URL/website-address that gives. Just the URL/website-address. You may need to run that script twice (the first time with root permissions to update in the /usr/sbin directory, and the second time to get the URL).
Note if for some reason that gives you no website/url/address then run it with the no-upload option:
and post the file /etc/alsa-info.txt it creates to Pastebin.comand press SUBMIT on that site and again post here the URL/website-address it provides.
… some clarification on running the script “alsa-info.sh” … when you run:
you should get something like this (if it asks for an update, select NO):
followed by this (select the SHARE/UPLOAD option):
followed by this (its quickest if you simply select ‘NO’ to seeing the output - you will see it on the web page) :
followed by this (where in RED is the URL).
Just post the URL you get (similar to the RED URL in my example, but yours will be different).
Again, if you can not get that, then run this with the no upload option:
which will create the file /tmp/alsa-info.txt. Copy that file and paste it on [Pastebin.com](http://pastebin.com) and press submit. That will give you a URL address. Please post that URL here.
