Bug#791642: pavucontrol: reports incorrect output device information

[Andrew Kane]

Package: pavucontrol
Version: 3.0-3
Severity: normal

Dear Maintainer,

My motherboard has 3 rear audio ports. pavucontrol reports one of them as a mic jack, and the other two as Line-Out and Headphones.
I can't verify that this report is correct, because I can't read the symbols on the motherboard riser where the jacks plug in.

I have a headphone amplifier and a set of amplified loudspeakers. I would drive them separately using the Line Out for the speakers and Headphones for the headphones.

When I plug the input of my headphone amplifier to Headphones pavucontrol reports it as unplugged. 
When I swap the Headphone and Line Out inputs pavucontrol reports the Headphones output unplugged.
When I plug the headphones directly into the Line Out port I get sound; when I plug them into the Headphone jack I get no sound.
Regardless of the disposition of the plugs, switching between the Headphone and Line Out devices in pavucontrol only changes the level of the output on the device plugged into Line Out; the one plugged into Headphone is unaffected.


I suspect that what's happening is that the jack which pavucontrol reports as a Headphone port is actually an input port (presumably a Line In, since there's already a Microphone port.)
I don't know why pavucontrol is controlling the level of the same output under the labels of two separate outputs.
I will try to remap the port which pavucontrol calls a Headphone port so that it really is one, if I can figure out how to do so, and append to this report if I am successful.
