headphones working while speakers not working

[Daniele Pirani]

to change kernel does not help, I tried 3.11 kernel, 3.8 kernel, 3.5 kernel.

Testing the left and right channel work for headphones output , a minijack is connected to the ampli.

Removing the jack the notebook ( system76 notebook) is like mute. I have tried to use alsamixer , all the volume are ok.
application seem to output their audios... but nothing to through the speakers.

thanks

you have to report upstream since hda-analyzer crash at viewing node 0x24

may be related to the balanced pincap

sorry , but I don't know what do you mean with "you have to report upstream " , what have I to do??

and I totally don't understand the rest of the sentence :
" since hda-analyzer crash at viewing node 0x24

may be related to the balanced pincap

Pincap 0x00010050: OUT EAPD Balanced
  EAPD 0x3: BALANCED EAPD "

you driver seem quite old since the name of device 2 should be alt analog instead of hp and only one capture subdevice when auto Mic selection is enabled for notebook after via codec using generic driver
