Dear Maintainer,

after updating an Asus eee netbook from Debian 8 to Debian 9, the internal
speaker fell silent.

This happened on 2 different eepc netbooks (one using .

Details: headphones work as intended,
	 speaker: no sound despite signal shown in pavucontrol
         Audio Device: Intel NM10/ICH7

Note:
  Before the update, pavucontrol listed 3 outputs:
  audio, speaker, and headphone.  "audio" worked.

  After the update, the "audio" port is missing on the list.

I could "fix" (work around) the issue with help from

I currently use a modified
/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf
as a new udev rule would require to rebuild initramfs.


I reported the issue to the pulseaudio mail list but did not get a response.


Thank you,

This suggests that relevant change is in the kernel. Did you try
booting with the old kernel?

Booting with 3.16 did not make a change.

The following patch fixes the problem for my EeePC netbooks:

Background:

The alternatives profile sets
``/usr/share/pulseaudio/alsa-mixer/profile-sets/force-speaker.conf`` and
``…/force-speaker-and-int-mic.conf`` load rule sets that mute the
internal speaker instead of turning it off.
They can be used instead of the earlier proposed additional rule set.


For users that don't want to wait for the fix in the package, there is a
quick workaround: Create a new file ``91-pulseaudio.rules`` (following example
https://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles/)
with the content:

      SUBSYSTEM!="sound", GOTO="pulseaudio_end"
      ACTION!="change", GOTO="pulseaudio_end"
      KERNEL!="card*", GOTO="pulseaudio_end"

      # Asus EeePC R11CX

Thanks for the patch. I think this is something that should go
upstream. Could you submit this to the upstream mailing list? Upstream
might have comments/questions and I wouldn't be able to answer them.
The upstream list is pulseaudio-discuss@lists.freedesktop.org.
