No sound on notebook Conexant CX20561/MCP67 with openSUSE 12.2

[Panchux]

Hi all openSUSE gurus,

A time ago I posted this problem but with openSUSE 12.1 but my hdd died and it took with it some files and the sound configuration. I search the forum and web and found this codec, Conexant CX20561 (Hermosa) or 5051, gave headaches to everybody. In this very forum you can find two threads of HP notebooks with the same motherboard with similar problems:

https://forums.opensuse.org/english/get-technical-help-here/applications/391158-no-sound-alsa-hp-pavillion-dv6736nr.html

In those threads they managed to get sound working but I just can’t. This is my configuration:

Now the sound part, 50-sound.conf

options snd-hda-intel model=thinkpad
options snd slots=snd-hda-intel
# M71A.k5JPLyF5+X5:MCP67 High Definition Audio
alias snd-card-0 snd-hda-intel

I need to say that I tried every model related to Conexant codecs (laptop-hpsense, laptop-micsense, laptop-hpmicsense, benq, laptop-hp530, laptop, laptop-hp, laptop-eapd, hp, hp-dv6736, hp-f700, ideapad, toshiba, hp-laptop, asus, dell-laptop, dell-vostro, olpc-xo-1_5, thinkpad)

You can see the alsa-info.sh results here: http://www.alsa-project.org/db/?f=c977ae91ee33af5a2c9b48f1c8009a613ee9137d

I need to mention that after every change I rebooted or restart the sound service with rcalsasound restart and corrected the volume with alsamixer and pavucontrol and tested with

aplay -vv /usr/share/sounds/alsa/Front_*
speaker-test -Dplug:front -c2 -l5 -twav

I also add my user to audio group and tried login in with root user but root does not have sound either. I also did a chgrp -R users /dev/snd
To my surprise the very same problem showed up with Ubuntu 12.10 and Fedora 18, so this issue is not openSUSE related but ALSA or kernel.

Any thoughts and ideas will be much appreciated,

Pancho

I kept investigating and focused on HP laptops with similar hardware and working sound. I realiced someone complained abut mic not working only and I read he used the model “auto” which it was not listed under any Conexant codec. I tried it and a new set of channels appeared. Still no sound until I thought on disabling the Auto-Mute option.

Sound is now working but, obviously I have no MIC nor Headphones. So the solution to have sound is to have the 50-sound.conf like this

options snd-hda-intel model=auto
options snd slots=snd-hda-intel
# M71A.k5JPLyF5+X5:MCP67 High Definition Audio
alias snd-card-0 snd-hda-intel

This may apply to these HP/Compaq laptops

Again, any thoughts or ideas of how to get mic/headphones working would be much appreciated.

Thanks - there is a lot of information in your post, and it will take a while to digest.

I note you have alsa-1.0.25 installed, replacing the stock alsa-1.0.24

I note you have Kernel release: 3.4.28-2.20-desktop. I note you have the rpm alsa-driver-kmp-desktop-1.0.25.20130308_k3.4.33_2.24-1.1.x86_64.

Kernel 3.4.28 is not the same as 3.4.33. Ergo you may have the wrong rpm or wrong kernel version installed for this to work properly. That in itself could break things. As much as is practical those versions should be the same. That ‘might’ (and might not) be contributing to the problem. In all due honesty, I don’t know. I can not always figure out what the openSUSE alsa packager has in mind with various alsa kmp updates.

@Panchux

I need to say that I tried every model related to Conexant codecs (laptop-hpsense, laptop-micsense, laptop-hpmicsense, benq, laptop-hp530, laptop, laptop-hp, laptop-eapd, hp, hp-dv6736, hp-f700, ideapad, toshiba, hp-laptop, asus, dell-laptop, dell-vostro, olpc-xo-1_5, thinkpad)

I cchecked the HD-Audio-Models.txt for the Conexant 5051 (which I believe is the same as the CX 25061 and I note for alsa-1.0.24:

Conexant 5051
=============
  laptop    Basic Laptop config (default)
  hp        HP Spartan laptop
  hp-dv6736    HP dv6736
  hp-f700    HP Compaq Presario F700
  ideapad    Lenovo IdeaPad laptop
  lenovo-x200    Lenovo X200 laptop
  toshiba    Toshiba Satellite M300

and I note for alsa-1.0.25

Conexant 5051
=============
  laptop    Basic Laptop config (default)
  hp        HP Spartan laptop
  hp-dv6736    HP dv6736
  hp-f700    HP Compaq Presario F700
  ideapad    Lenovo IdeaPad laptop
  toshiba    Toshiba Satellite M300

The lenovo-x220 option was removed between 1.0.24 and 1.0.25. That would suggest no need to test ‘lenovo-x200’, but while I am not saying that will work, but you could try that instead of auto.

I assume you also tried testing with NO model options ?

What sort of record tests have you attempted with your mic ?

You posted this script link: http://www.alsa-project.org/db/?f=c977ae91ee33af5a2c9b48f1c8009a613ee9137d . I note that is with the ‘hp’ model option and not relevant to your current setup. Please post a link to an alsa-info.sh script output that reflects you current configuration, and not some disgarded configuration.

Ultimately you may need to write a bug report on openSUSE to obtain the openSUSE alsa packager’s attention (where that packager is also a sound driver developer). Looking at alsa-1.0.24 to 1.0.25 changes for the Conexant 5051 I note this:

@alsa-project page

• ALSA: hda - Keep EAPD turned on for old Conexant chips
  In the old Conexant chips (5045, 5047, 5051 and 5066), a single EAPD may handle both headphone and speaker outputs while it’s assigned only to one of them. Turning off dynamically leads to the unexpected silent output in such a configuration with the auto-mute function. Since it’s difficult to know how the EAPD is handled in the actual h/w implementation, better to keep EAPD on while running for such codecs.

Is that relevant ? I have no idea as it is way above my head technically. Hence the need to pull in the REAL expert.

There is guidance here for bug reports: https://en.opensuse.org/openSUSE:Submitting_bug_reports

Thanks and good luck.
