Description Joonas Saarinen 2016-05-16 13:49:11 UTC

Fujitsu Siemens U9210 laptop with Realtek ALC262, Ubuntu 16.04 x86-64

http://www.alsa-project.org/db/?f=0921dd56f8efdb74e605114403f9bc74dd9b4536

Adjusting headphone volume does not have a real effect.

The keyboard volume keys seem to work normally and the volume bar appears on screen. However, the actual volume does not change. It seems to be stuck at about 10% level (rough estimate). Changing volume in Alsamixer has no impact either.

When headphones are plugged in, the audio output is switched to headphones as expected.

Changing internal loudspeaker volume works properly.

I am not sure if this is an ALSA or Pulseaudio bug.

Adjusting the output volume of the docking station headphone output seems to work as well, although this output seems to have a lot of electric noise (I can hear keyboard typing, CPU frequency stepping, etc.).

Comment 3 Joonas Saarinen 2016-05-16 15:59:00 UTC

Okay, I am getting somewhere.

It seems that after plugging in the front headphones, the 'Speaker+LO' mixer setting is automatically set to 0%. It has to be manually set to 100% every time after plugging in front headphones (amixer -c 0 sset 'Speaker+LO' 100%). Then I have a working volume control. What kind of fix is required?

What comes to the dock headphone noise, I tried disabling Loopback Mixing, but it did not help in this case. Maybe the dock is simply electrically badly designed. The sound quality of the front headphone jack is excellent.

you need to vhange pulseaudio conf so that it won't switch off the headphone volume
