12.04 64bit sound works only in headphones

**Magrim** · February 21st, 2013

Hello.

Just bought Dell Inspiron 15z 5523. Sound worked fine in Windows 8.
After installing Ubuntu 12.04 64bit, sound only works through headphones. Built in speakers are silent.

~# cat /proc/asound/card0/codec#* | grep Codec

Code:

Codec: IDT 92HD91BXX
Codec: Intel PantherPoint HDMI

~# aplay -l

Code:

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: 92HD91BXX Analog [92HD91BXX Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

also checked alsamixer, and usual audio controls (and pavucontrol).

tried to add records in /etc/modprobe.d/alsa-base.conf like:
options snd-hda-intel model=auto

It`s for four evenings I googled and tried different solutions. Please, can you suggest something to me? Maybe I missed something obvious?

Well done for having a go at doing it yourself and explaining the steps you already took. There is one very obvious route of inquiry you followed - Google!

which can still yield more results.

I Googled for ubuntu "Intel PantherPoint HDMI" and found this:

Look at the second last response in that bug report, by Mark Rijckenberg:

Your PC's soundcard contains a very new sound codec called ALC280.
Please install the patch alsa-hda-dkms_0.1_all.deb as explained in #3 in the following bugreport:

So presumably all you have to do is install this .deb file

https://bugs.launchpad.net/ubuntu/+s...ms_0.1_all.deb

and it should fix your problem. Let's hope it works!

Thanks for trying.

I wasn`t able to install this patch (make.log is attached):

Code:

Error! Bad return status for module build on kernel: 3.5.0-24-generic (x86_64)
Consult /var/lib/dkms/alsa-hda/0.1/build/make.log for more information.
dpkg: error processing alsa-hda-dkms (--install):

In that bug report I also checked a previous message, and run a command

cat /proc/asound/{version,cards,devices,hwdep,pcm,seq/clients}

Code:

...
00-03: HDA Codec 3
00-00: HDA Codec 0
00-00: 92HD91BXX Analog : 92HD91BXX Analog : playback 1 : capture 1
00-03: HDMI 0 : HDMI 0 : playback 1
...

So it seems that my codec is not ALC280.

Also I updated ALSA drivers, using this guide:
https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

The package I installed is: alsa-hda-lts-quantal-dkms_0.201302210020~precise1_all.deb

OK, sorry about that. Here is a bug report affecting 92HD91BXX which you appear to have. The solution suggested is to try kernel 3.7.

https://bugs.launchpad.net/ubuntu/+s...r/+bug/1091871

It's always worth looking around on Launchpad for solutions because the solutions suggested are often provided by the developers themselves.

I tried following kernel versions:
3.6.0
3.7.0
3.7.9
3.8.0
3.8.0 from daily folder

with some of them interface (and sudo command in terminal) got frozen.
with all of them speakers and wi-fi haven`t worked.

I also checked all four bug reports on launchpad and tried some solutions.

I think my last hope is to file a bug report to bugs.launchpad.net .

On a positive note: I found a pipe symbol on my keyboard
