[gentoo-user] no sound through headphones (OK through speakers)

[gentoo-user] no sound through headphones (OK through speakers)

[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 three different ones).

The sound settings gui recognizes that headphones are in.  The sound
test is silent.  If I select the internal speakers in the gui (with the
headphones still in) sound is fine.

Is there some headphone option I must enable in the kernel or elsewhere?

thanks in advance.

PS I also tried cat /boot/vmlinux > /dev/audio1.  Silent on headphones

The volume is probably muted for the headphones. Install pavucontrol,
and execute it while the movie is playing. In the "Output Devices" tab
look for your sound card (probably something like "Built-in Audio"),
and in port select "Headphones". Then adjust the volume.

Thank you (and robot1).  I installed pavucontrol and followed your
instructions.  The volume was selected in the middle (100%).  We see a
volume meter going up and down as expected with either headphones or
speakers selected.  When mute is pressed the meter looks dead, as
expected.

It also shows line-out is unplugged and headphones are plugged it.

Any thoughts.  I appreciate the help.

Maybe the headphone amp or the headphone socket of your soundcard is 
broken. Plug the speakers into the headphone socket and test if you 
can hear something. For my experience you can do that without the risk 
of killing something, but of course I can give you no guarantee. :-)

I can't do that this week.  I can try it next week at home where I think
I have speakers that plug in.

If your headphones are headsets with microphones it maybe could be 
that the headphone socket of the soundcard isn't compatible with 
the plugs of the headphones. But that's just a thought. I never had 
a soundcard where this was the case.

They are just earbuds, no mic.  But maybe the port of the laptop assumes
a mic + headphone (i.e., three signals mic, left "ear", right "ear" as
used for cell phones.  I have one of those at home I can try this
weekend.

It will remember the volume/mute settings per device. Is it unmuted
and turnt up?
