Please help me. I can't work without headphones :(
I have weird issue with my headphones - they do not work in entire laptop (windows and ubuntu). I have dual boot.
That behavior started about two weeks ago. I can't realize what actually happen, i do nothing special - everything as usual.
Whereas speakers works fine on both windows and ubuntu.
Occasionally sound in my headphones returns by random reason and disappear also randomly.
This is output of alsa script: http://www.alsa-project.org/db/?f=179e2b87b66b9c12c0b9aa2a5a436ed23751b7a9
In ubuntu sound settings i see nothing wrong - two options speakers and headphones: Ubuntu sound settings
When i chose speakers sound appear, but when i change it to headphones i hear nothing.
I try to resolve that issue by run command below:
echo "options snd-hda-intel model=auto" | sudo tee -a /etc/modprobe.d/alsa-base.conf
I do that command and reboot the system but nothing happen. Still no sound.
I've also installed pavucontrol: pavucontrol output
Silence indicator leap but i hear nothing when headphones plugged in.
Another thing that i do is to see output of AlsaMixer:
Also nothing special, everything in order.
Maybe reason of that behavior HDA Intel PCH and HDA Intel HDMI conflict?
I have two additional displays that connect to laptop through HDMI - may be here lies the secret.
In windows system also there are no headphones sound , by default chosen HDMI sound card. When i try to switch to another intel sound card nothing happen - still there are no sound in headphones but in speakers there are.
