HP550: No sound from laptop speakers, only from headphone in karmic

[Roland Meier]

After upgrading to karmic (or after one of its normal updates - sorry) I had no sound output from the speakers from any application on my HP 550 laptop.
Sound output via headphone works, and speakers were no problem before in jaunty either.
I installed linux-backports-modules-alsa-karmic-generic with no effect.
After installing the updates from https://launchpad.net/~ubuntu-audio-dev the headphones also stopped working with the default configuration (no model= parameter for the snd-hda-intel module). They now work again with "options snd-hda-intel model=basic" or "model=hp" in /etc/modprobe.d/alsa-base.conf .
Most information should be in http://www.alsa-project.org/db/?f=1fad068e798f0fdc7563ba137172b7e4e9db9503
or http://www.alsa-project.org/db/?f=c1b7e0021d187f0f5b6dd55eb148784fc7e6a5ed
There are lots of similar bug messages here, none of which helped, so I picked the most similar one https://bugs.launchpad.net/ubuntu/+source/linux/+bug/245062 and added my current information. Now I issued this new one as recommended by Daniel T. Chen.
Please tell me how to help any further.

Please use apport-collect -p alsa-base 492303

(In the future, when filing bugs, please use ubuntu-bug instead. It attaches relevant info and eliminates this unnecessary round-trip pinging.)

[Roland Meier (rm369)]

I would have done if I could. It doesn't get through this password needing proxy here (apt-get does), and I can't seem to find a way to put this information in a file and attach it here either.

roland@hp:~$ apport-collect -p alsa-base 492303

Maybe you could just tell me what information to add?

[Roland Meier (rm369)]

And concerning your request in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/245062/comments/6 :
I installed and tried today's kernel linux-image-2.6.32-999-generic_2.6.32-999.200912031148_i386.deb .
No sound from speaker or headphone with model=hp, headphone only with noch model= argument, otherwise noch change at a first glance (my WIFI didn't work either). Should I provide an alsa-info.sh output or anything else with this config?

Today's kernel image is not sufficient. You need an actual tarball of
alsa-driver source code that you need to compile and install.

[Roland Meier (rm369)]

OK, here we are with your current snapshots and 2.6.32-999:
Headphone-only sound as before with model=hp, this time also with no model= argument. No speaker sound either way.

[Roland Meier (rm369)]

(sorry, same behaviour without model= argument, change with =hp)

[Daniel T Chen (crimsun)]

If you can't use apport-collect, please download
http://www.alsa-project.org/alsa-info.sh and use it as a bash script.

[Roland Meier (rm369)]

I did. In the initial post you can find 2 outputs with the newest ubuntu kernel, your latest alsa packages from https://launchpad.net/~ubuntu-audio-dev/+archive/ppa and 2 model= settings:
 http://www.alsa-project.org/db/?f=1fad068e798f0fdc7563ba137172b7e4e9db9503
 http://www.alsa-project.org/db/?f=c1b7e0021d187f0f5b6dd55eb148784fc7e6a5ed
In #7 I attached the script output with today's bleeding edge kernel and your latest driver and libs on your homepage.
Sorry for not pointing at it clearly enough.

Hi again,
after I saw that I also have no sound in a fresh boot of some live CDs I sent this laptop to HP for a warranty repair, and they replaced the built-in speakers, so there probably was some hardware problem. Sorry...

Now maybe as a consequence of all my tries before I still have a problem:
Immediately after booting I have no sound from any application, neither from speaker nor from headphone.
All channels in alsamixer are unmuted and at max level.
alsa-info.sh yields:
http://www.alsa-project.org/db/?f=a8efaf3ded0b5b2aed83cffc15ed1d03b2cafc76

If I do a
sudo alsa force-reload
now, start alsamixer and unmute all channels and set all levels to max everything works as it should, and the result of alsa-info.sh now is:
http://www.alsa-project.org/db/?f=f85ade26726c10bf8469b9d948b18ccd9a35a357

The difference that may cause the problem is in section "HDA-Intel Codec information":
...
Node 0x03 [Audio Output] wcaps 0x441: Stereo
  Converter: stream=5, channel=0
...

After the force-reload the value after stream= changes to 0 (as in the other three occurences).

The other remarkable difference is the line
HDA Intel 0000:00:1b.0: PCI INT A disabled
in the dmesg output the moment the force-reload is done (the other lines are the same in both configurations).

Nothing changes between both load processes. I set model=hp in both cases. Trying probe_mask=1 didn't change anything.

Something else I noticed is that I have two different hda-intel modules, one from a backports package, the other from the generic kernel package:
$ find /lib/modules/2.6.31-17-generic/ | grep hda-intel|xargs ls -l
-rw-r--r-- 1 root root 43192 2009-12-10 20:35 /lib/modules/2.6.31-17-generic/kernel/sound/pci/hda/snd-hda-intel.ko
-rw-r--r-- 1 root root 43792 2009-12-11 07:29 /lib/modules/2.6.31-17-generic/updates/alsa/snd-hda-intel.ko
(Probably that's irrelevant, since I booted the 2.6.31-14-generic kernel, which is th last to have only one module, and nothing changed).

Sorry for the confusion with the defect hardware. Probably this is now a completely different problem, the headline doesn't fit any more.
Maybe someone can help me here (what option can I chang to manually set this stream= setting to 0?), so we can close the issue completely. If you want me to I'll open a new case.

Hi, and merry christmas :)
I upgraded to the newest ALSA versions with no effect:
Driver version: 1.0.21
Library version: 1.0.22
Utilities version: 1.0.21

State after reboot, all channels unmuted and at maximum, no sound output:
http://www.alsa-project.org/db/?f=56ce8892359ae80bf75d2d3b7f5797884ebfa94d
("stream=5", no "HDA Intel 0000:00:1b.0: PCI INT A disabled", "Subdevices: 0/1")

State after
sudo alsa force-reload
alsamixer + unmute all channels and set all to maximum (default is muted)
(Sound output works perfectly):
http://www.alsa-project.org/db/?f=f6ab3e85d28bfff2521b00371047eb5bd0af1084
("stream=0", "HDA Intel 0000:00:1b.0: PCI INT A disabled", "Subdevices: 1/1")

force-reload output:
$ sudo alsa force-reload

_Please_ tell me what to do so that I get the force-reload state immediately after reboot - thanks!

Hi again,

sudo alsactl store 0
in the working state after the force-reload and unmuting seems to have done the trick.
Thanks again, sorry for bothering you, merry christmas and a happy new year 2010!
