I've got no sound [attachment inside]

[kingoslo]

Hello there,

I've got no sounds from my audio card. I have established this knowledge by confirming it by using two seprate sets of speakers.

In addition, there is a weird muted icon in the top left corner. I've looked through the sound settings, including alsamixer, and I cannot find whats muted.

Please see attached screenshot. As you can see, my output it muted, but the speaker is back (see a) in screenshot), not white like it normally is (see b) in screenshot).

Can somebody please help me restore sound from my audio ports?

Thanks.

Kind regards,
Marius

Hello

If you've not already tried them, I'd recommend these two troubleshooting articles for sound issues under Ubuntu:

https://help.ubuntu.com/community/SoundTroubleshooting

https://wiki.ubuntu.com/DebuggingSoundProblems

Yes, I have already completed both of them, and unfortunately they didn't help

Kind regards,

Bump!

I ran through this guide again: help[dot]ubuntu[dot]com[slash]community[slash]SoundTroubleshooting (because of the forums policy, I cannot write the URL straight out. It is forbidden for all users who has not yet made 15 posts. I am sorry for that.

I ran through the alsa-part again, I noticed that the information that the guide states should be there, isn't on my computer.

In the guide (help[dot]ubuntu[dot]com[slash]community[slash]SoundTroubleshooting), none of this information were to be found, so I couldn't complete the guide:

Now I have to figured out what Codec my soundcard uses. This is also on the webpage with my sound configuration.

It has a section that looks like this:

!!HDA-Intel Codec information
!!---------------------------
--startcollapse--

Codec: SigmaTel STAC9227
Now take a look at ALSA-Configuration.txt again, and you will find a section that looks like this, which matches up with my soundcards codec:


STAC9227/9228/9229/927x
ref Reference board
3stack D965 3stack
5stack D965 5stack + SPDIF
dell-3stack Dell Dimension E520
dell-bios Fixes with Dell BIOS setup
A stack is the same as a jack plug in your soundcard.

By inspecting your computer you have to figure out how many jacks you have on your soundcard. I have six jacks in the back and two in the front of my computer, so I chose the 5stack model configuration.

So armed with this knowledge, it's about time to start configuring your system.

This is the steps that were necessary to get a Dell Dimension E520 with Intel HDA and SigmaTel STAC9227 Codec to work after upgrading to Ubuntu 9.04:


sudo nano /etc/modprobe.d/alsa-base.conf
This part will depend on your soundcard, it consists of the module name (snd-hda-intel) and the model I found in ALSA-Configuration.txt, 5stack:

options snd-hda-intel model=5stack
