laptop speaker working, headphones jack no

[lucadedalus]

Hello everyone, I use Ubuntu with kxstudio repos on my Dell Inspiron laptop.
I was doing all right, I was beginnig to explore audio-linux world
Then, I upgraded Ubuntu from 14.10 to 15.04 ..
Since then, laptop speaker is working but headphones jack no!
I am running a lowlatency precompiled kernel, with Jack and Pulseaudio bridge.
Since I am a beginner in some way to audio configuration in Linux, can you help me in finding where is the problem?
Thanks!!!!

Luca

Try

Code: Select all

alsamixer

in the terminal and adjust the headphone volume via the arrow buttons on your keyboard.
There should be a headphone fader...

There seems to be something wrong with alsamixer..
I have no fader at all, just 3 number like

00 00 00
<S/PDIF> <S/PDIF 1> <S/PDIF 2>

no editing is allowed.
maybe there is a way to reconfigure alsa?
thanks

Thanks, I have 2 choices:
- 0 HDA Intel HDMI
- 1 HDA Intel PCH

With the second one (pch), I see the fader and the headphone volume and headphone Mic where muted - wow!
I raise the volume, but still no sound can be heard, mm..
I tried to reboot but it is the same.

JACK already seems to be using PCH.
In Cadence -> configure I can see 5 options of output:

hw: HDMI,3 [HDMI 0]
hw: HDMI,5 [HDMI 1]
hw: HDMI,7 [HDMI 2]
hw: PCH, 0 [ALC3234 ANALOG]
hw: PCH


And now is set to the last one. I also tryied the other PCH but the same result.
Which is the right one?
Thanks

Ok now it is working!
I misenderstood the fatc that the volume was 0 but the channel else was muted.
I will look if there is something changing the alsa settings on startup.
Thanks a lot!
