How to connect the jack sink with headphones ?
Posted: Mon Jan 08, 2018 1:54 pm
The problem is, when I start the jack and plug the headphone in, the sound from the speakers stops, but there is also no sound in the headphones.

I found a tutorial with the same case at http://tedfelix.com/linux/jack-headphones.html
1. But, I do not know how many channels are on my sound card. How to know the number of my soundcard channels?
2. Although I do not know, I keep trying the tutorial. I got to the stage of typing
Then the error appears
maybe it's because I installed jack2-dbus instead of jack. Then, how to solve it ?
Thank you
