No Sound After 12.1 Upgrade

I just upgraded my system from 11.4 to 12.1 and now my sound is gone. I have a volume control in the lower right corner. It is set to 100% and Mute is off. I tried Yast->Hardware->Sound. My sound card is there. When I play a test sound from there it works, but when I try to play a sound anywhere else I get nothing. I’m running KDE. Pulse is turned on. It seems like it should be working, but I certainly don’t hear anything. Any help is appreciated.

Did you check the master volume in Yast->Hardware->Sound ?

Also in System Settings > MUltimedia > Phonon
Check all the settings in there for the preferred device (I had to setup in here because I have more than one)

Thanks for the reply.

In Yast, the master volume is set to 90% and “Test” works quite well. Scared the **** out of me. :slight_smile:

However, System->Mulitmedia->Phonon doesn’t appear to be quite right. For each entry under Audio Playback it lists “Dummy Output” as the Playback Device. I clicked on the Audio Hardware Setup tab and the Sound Card pull down is ghosted out. Can’t click on it at all. I can click on the Sound Device pull down, but it is blank. There are no choices at all.

This doesn’t seem right to me. The Audio Recording list has a couple of devices under each entry, so it seems like the Playback section should too. It seems like I should have some choices or at least be able to see something in the pull downs in Hardware.

Any ideas? Thanks again.

Show me a screen shot of the system settings/multimedia/phonon section

I had the same problem. Make sure, your user is in the “audio” group and
Logout/Login. Worked for me.

For me it did work to remove the audio device in YaST and reinstall it.

Here are both tabs. (Wasn’t sure how to do this, so I tried it two ways.)

Thanks, but no such luck here. I added the audio, and then phonon and phonon-access groups for good measure. Still no sound. :frowning:

Thanks. I gave this a try too. I figured this had to do the trick. Didn’t make any difference.

It seems like it has to be a Phonon problem since it works fine from Yast. I’m stumped. I don’t know anything about Phonon.

The stock guide to Audio issues is here:
SDB:Audio troubleshooting - openSUSE

From the Images you posted of ‘Dummy’ device. Looks like whatever you have is not recognised.

Take a look at the guide and see if you can tell us what audio hardware you actually have.
This in a terminal will get you hardware info that might help:
/sbin/lspci -nnk

Thanks. I’ll take a look through that guide in the morning.

Here is the output of that command.

This is your device
Perhaps that will help you set it up correctly in Yast > Hardware > Sound

ahh … thats ‘bad’ measure and not good. Just stick with adding your regular user to group ‘audio’. Don’t over do it, for if you do not know the underlying code, excessive permissions could in turn break things.

To confirm that you were successful in adding your regular user to group ‘audio’, please open a terminal and type “groups” and post here the output.

Note also, after adding your regular user to group ‘audio’ you MUST log out and log in of GNU/Linux … ie NOT just the desktop, but of GNU/Linux. A restart is often the quickest way to do this.

Not sure how or why, but when I logged in tonight I had sound. No one has touched this computer since I posted my last response last night. It has just been sitting here running the whole time. No reboots or restarts. I had logged in and out of it several times over the course of working this problem and that didn’t help, so I’m not really sure what fixed it. Rather than just “Dummy Audio” in my devices, I now have an Internal Audio Device. The hardware tab is populated too. (See the screen shots.)

While I wish I knew what fixed it, I’m not going to look this gift horse in the mouth. I’ll take the “win” and move on.

Thanks to all of you for your help. I’m sure something in there was the fix, I just don’t know what it was.

Merry Christmas!

Possibly adding your user to group audio fixed it (coupled with a reboot to restart the loading of your alsa sound driver).

When you say logged out and logged in several times, do you mean of your GUI ? or of openSUSE GNU/Linux. They are not the same.

I know of cases where users added themselves to group audio, and were told they needed to log out and log in openSUSE GNU/Linux and they only logged out of KDE (or GNOME) and they thought that sufficient. Its not. Then after a reboot, sound ‘miraculously’ started working.

And also, once one is added to group audio, the alsa audio driver needs to be restarted. This can be done via command, or via YaST, or by restarting.

… Which is why sometimes the easiest way to advise users is to suggest they reboot, although ‘rebooting’ in GNU/Linux is against the philosophy that many of us have wrt GNU/Linux.

Anyway, … glad to read it works now.
