JACK Audio: How to make Headphones work ?

Post by escarneiro »

Guys,

Using a snd-hda-intel card (ALC1220) and pulseaudio on top of Jack.
Everything is working (except for some random choppy sound sometimes, that make me change config on the fly).
I have a frontal 3.5mm that I use for headphones. When plugging headphones, the line out (in the back) is muted,
but I got no sound on the headphones. On the other hand, front capture works well.
Is there any extra config I have to do ?

Check if the headphones are muted by alsamixer (un/muting can be done by pressing 'm'). This happens for me from time to time without any noticeable reason.

If not:
What are playback_3,4,5 and 6 ? Try connecting each PulseAudio Port to each playback port and see if you get a signal in any configuration.
