No sound after OpenSuSE 12.3 upgrade

English Install/Boot/Login
#1

Hi,

I just upgraded my 64bit OpenSuSE 12.2 to OpenSuSE 12.3 and found that there is no sound from the speaker.
From YAST/Hardware Information, three audio devices are listed which includes the loaded driver modules, same
as before the upgrade. However, from the Sound settings box, only a dummy output is listed in the sound output
device box, instead of three devices as before. This explain the no sound problem.

Any idea on how to solve the problem?

try installing “pavucontrol” and launch pavucontrol through Alt+F2 launcher and configure the card in it

#3

Thank you very much, I installed and launched pavucontrol, however, there is no hardware output devices listed to be configured. Something is missing.

I wonder there might not be a problem if I installed OpenSuSE 12.3 as a new installation, instead of upgrading from an existing OpenSuSE 12.2?

#4

can we launch the same with kdesu pavucontrol in Alt+F2 and check hardware again

Do an online update. There’s a bug fix that just came out in the last
couple of days.

Did you remove and restart the devices? ie force the system to look at setting up sound again.

Do you really have 3 sound cards? I doubt it so somthing is amiss

#7

Thats strange. The kernel should automatically identify your cards and configure alsa.

Please can you run a diagnostic program (with your PC connected to the internet) to provide us with more information ? In a terminal send the command:


/usr/sbin/alsa-info.sh

and select the UPLOAD/SHARE option and then when the program is complete finished, look in the terminal and copy the website URL where it uploaded the data and post it here on this thread. That might give us some insight into your problem.

Hello, I am experiencing the same problem, here is the link to my harware configuration:

Thank you!

Your mixer has your sound muted. From the diagnostic script output you posted:



**!!-------Mixer controls for card 0 [Intel]**

**Card hw:0 'Intel'/'HDA Intel at 0xd4340000 irq 45'**
  Mixer name	: 'Conexant CX20549 (Venice)'
  Components	: 'HDA:14f15045,103c30b2,00100100'
  Controls      : 26
  Simple ctrls  : 11
**Simple mixer control 'Master',0**
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 43
  Mono: Playback 0 **[size=3][0%][/size]** [0.00dB] [on]
....
**Simple mixer control 'Speaker',0**
  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 43
  Mono:
  Front Left: Playback 6 **[14%]** -55.50dB] [on]
  Front Right: Playback 6 **[14%]** -55.50dB] [on]

With Master volume at 0% and speaker volume at 14% your PC effectively has the sound muted. So move up the volume control setting levels in your mixer.

I had the same problem after an upgrade from 12.1 to 12.3: no sound. The “yast2 sound -> Other -> Play test sound” worked, however.

I tried the pavucontrol utility which properly showed me my audacious sound playing, but mentioned “no output device”. Strange.

Finally I disabled pulseaudio (Yast2 sound -> Other -> PulseAudio Configuration) then my sound worked. After enabling pulseaudio again, it still worked. So I’m happy now. pavucontrol now also shows my “internal audio analog stereo” output device.

HI All,
I am new to openSUSE. I also am having a hard time with my sound setup. It was working until I did a software update and then it stopped working.

I played with the settings in Phonon, and could not get it to work. I also installed pulseaudio and tried enabling/disabling it.
Not sure why the audio won’t work because the test sound does work. Is there a troubleshooting guide somewhere? These various control panels don’t make much sense to me.

Thanks,
Chris

I note from the script:


!!Aplay/Arecord output !!--------------------  APLAY aplay: device_list:267: no soundcards found...  ARECORD arecord: device_list:267: no soundcards found...

That does not look good. I’m thinking this could be a permissions issue.

Try adding your regular user to group ‘audio’. Reboot, and test.

#13

You could try to add your user to the group “audio”.
Type the following in a terminal window (replace $USER with your username):

sudo usermod -a -G video $USER

or open YaST->Security and Users->User Management. Select your user, click on “Edit” and switch to the “Details” tab. Activate the checkbox in front of “audio” in the list of secondary groups.
See also openSUSE 12.3: Chapter 10. Managing Users with YaST

Normally this shouldn’t be necessary, but maybe you have a permissions problem.

#14

Thank you wolfi323 and oldcpu, indeed my user was not a member of Audio.
It has been frustrating because sometimes I reboot and it works, sometimes it does not. When it does not work I get an ominous message that the OS cannot find my audio device and askimg me if I should let KDE forget about it. I say “no” of course. If I see that message again I will post it here.

Hopefully the permissions thing changes that.

Why doesn’t it set things up so the default user is a member of audio? That just seems like an oversight…

Thanks,
Chris

Silly question time: Why does it so often happen that the sound i/o gets muted? I had an upgrade recently (before today’s folly) wherein my mics and speakers got muted. I ran the alsa config thing and it only showed one output device at full volume. If I weren’t such a stubborn cuss, I’d have not figured out that you have to fiddle around with that thing until it shows all the devices and then figured out that not all devices are on the first page. Once through the horizontal scrolling, I found the reset devices, turned up the volume and all was fine.

Now, back to my question: Why does it so often happen that the sound i/o gets muted?

(P.S. I do not expect a serious answer. This is just venting my exasperation with this common event.)

#16

Well some cards/drivers need it some do not. In the past if you had a Soundblaster you had to be added to audio but most other card you didn’t.

#17

I changed the permissions as recommended and have had no further problems.
Many thanks!
