[gentoo-user] no sound through headphones (still bad)

[gentoo-user] no sound through headphones (still bad)

[allan gottlieb]

Hardware: Dell Latitude E7450 laptop

Gentoo essentially all stable
Gnome / Systemd

When I play a movie using totem it sounds fine if no headphones are
plugged it.

No sound at all with headphones.  I tried a few, one with a microphone
several without.

The gnome sound settings gui recognizes that the headphones are in but
the sound test is silent.  If, with the phones still in, I select the
internal speakers, all sounds well.

I installed pauvcontrol and selected "Output Devices".
When I selected "Speakers" as the port the volume meter moves around
normally and the sound is fine.
When I selected "Headphones (plugged in)" as the port the volume meter
again moves around normally but there is no sound.

This laptop dual boots windows.  I played the same movie on windows and
sound was normal both with the speakers and the headphones.

What should I try next?

thanks,
allan

check either with alsamixer and make sure the headphone jack isn't muted,
or look into pulseaudio if you're using that, although I can't help much
there as I don't use pulse.

I tried alsamixer with interesting results.  I used f3 [playback].

I first unmuted everything and tried to raise the volume of all.
I could raise the volume of all but the first headphone column

The columns from left to right are

Master Headphone Headphone Headphone Speaker PCM Auto-Mute et al
         ^^^^
           |
           could not raise this column
           
When the headphone is plugged in the second column is set to un-mute and
the speaker column is set to mute.  When the headphone is unplugged the
reverse occurs.  All this looks right.  But I can't raise the volume
setting for the second column (I can and did raise columns 3 and 4.

I sure looks like the headphone gets unmuted but is permanently at
volume 0.

Also the gnome volume control (top bar) shows headphone and when I move
its slider it raises/lowers the first column (master) volume.

To answer Alec's questions this is a 3.5mm jack.  Nothing new in dmesg.
sudo lspci | grep -i audio       shows
00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03)

I think/hope we are getting close and thank everyone for their help.

Just double checking; what is the value of these config keys in your
kernel config?

* SND_HDA_INTEL
* SND_INTEL* (there are a few of these)
* SND_SOC_INTEL* (there are a few of these)

I'm completely grasping at straws here. Another option may be opening up
a terminal and running:

    pulseaudio --kill
    pulseaudio --start --daemonize=no --verbose

Then try and use audio and see what exactly gets spit out.

Audio for me Just Works (tm), so I hope this helps.

Maybe? You could try reconfiguring your kernel with all of the Intel
audio-related drivers as modules, and see what happens.

It exited immediately because `pulseaudio --kill' did not actually kill
PulseAudio. Maybe try:

    pkill -9 pulseaudio
    pulseaudio --start --daemonize=no --verbose

Those are usually for smartphones and other System-On-Chip embedded
system. How about:

# grep CONFIG_SND_HDA_CODEC .config

It is possible that the headset runs off a different chip and
you're missing the codec driver for it. To check enable them all in
the same way you're building your other audio drivers (modules or
builtin). If it works you just need to figure out which one you
need and disable the rest.

Re: [gentoo-user] no sound through headphones (now works)

[allan gottlieb]

I cannot explain the following.

I was about the try the last suggestions (use kill -9; load more sound
modules) when I, just for fun, retried alsamixer.  I did the usual
unmute everything and it somehow just worked.

I did nothing new and would not be surprised if, during the next flight,
the headphones fail again, but it is clearly not a kernel problem.

Thanks you all for your help.

This looks like a kernel / ALSA level problem.  Not much sense in
messing with pulse settings IMO.

When wou run alsamixer, what do the Card: and Chip: lines say?

These files may be of interest:

/usr/src/linux/Documentation/sound/alsa/HD-Audio*.txt

You may have to pass some parameters to the snd_hda_intel kernel
module.  You'd do that by editing /etc/conf.d/modules, for example
adding this:

module_snd_hda_intel_args="model=3stack"

USB or 3.5mm jack?

What does running `dmesg' output around the time that you plug in and
unplug your headphones? Around the time that you start a movie/music?

What about `lsusb', `lspci', etc?
