No sound Ubuntu 13.04

[AK]

No sound can be produced in any possible way; In the sound settings, only Dummy Output is given as sound device;
There is the second OS installed (Windows 8), there is no problems with sound there, so it is not a hardware problem.

In the files attached, is the output of alsa testing script (alsa-info.sh).

Check your dmesg for an error like this:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1169984/comments/2

It's probably a duplicate of that bug

dmesg output is attached;
sound card seems to be detected (lines 882-883)

[Luis Felipe Marzagao (dulinux)]

Hello, dear friends:

Same thing here with the exact same audio card and Ubuntu 13.04.

00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)

I don't think it's a duplicate of those bug reports, because I don't see the reported bug messages in my dmesg.

In fact, the sound card seems to be detected just fine. But in the sound preferences I only get the S/PDIF (internal audio) and not the expected Built-in Audio (Digital Stereo IEC958). Thus, I don't get sound neither from the headphones nor the built-in speakers.

If I live boot with Linux Mint 13, sound works right out of the box.

I already tested my Ubuntu 13.04 with the main line kernel and the oem-audio-hda-daily-dkms_0.201305250346~raring1_all.deb, but no success.

Booting with Ubuntu 12.04 did not work either.

Please, find attached the result of alsa-info.sh script.

If there's any way of providing more info, please, give me directions.

Thanks.

[Luis Felipe Marzagao (dulinux)]

Here goes the alsa-info script results.

@Luis, I would suggest looking in alsamixer and toggling some of the settings as well as making sure nothing's muted.

[Luis Felipe Marzagao (dulinux)]

Daniel, thank you a lot for the tip. Indeed, when I entered alsamixer, it showed two playback devices, S/PDIF and S/PDIF 16.

The first on was showing a square wih '00' inside and the second was showing 'MM' inside (see attached screenshot).

It always happen if you liveboot from ubuntu or do a fresh intall. (Same thing does not happen with Linux Mint, which is strange - both devices always come unmuted by default).

After a little struggle, I discovered that pressing 'm' on the keyboard would change the status from 'MM' to '00' on the second playback device. Then I started having sound. :)

So, apparently, it seems the problem is solved. It has worked with 13.04 default kernel and with the latest one from the default repos as of now (3.8.0-19 #30), as long as I manually unmute the S/PDIF 16 after installing Ubuntu.

But if I turn the computer off. When I turn it on again, although the S/PDIF 16 comes unmuted, I must press the volume key on the monitor (it's a LG All in one computer) to get the sound working. If I don't press the volume key, there's no sound at all from the speakers.

On Windows 8 (that unfortunatelly came installed), it works without having to press the volume key after turning the computer on.

Maybe the fact the S/PDIF 16 playback gets muted by default has something to do with this 'volume key' issue. I don't know and any help debugging it would be mostly appreciated.

Thanks a lot.

I am using Kernel 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

and the problem persists, contrary to what is reported in the duplicate bug. The description of the
bug, and its workaround, are exactly the same as those of Luis Felipe.

Therefore, I'm not sure this a duplicate of the other bug, which appears to be solved in a previous kernel version.

[Daniel Letzeisen (dtl131)]

@Leandro: Luis was not the original reporter of this bug, nor is it clear if his issue was the same as the OP's. To avoid confusion, please file a new bug report.
