When I boot, PulseAudio defaults to sending output to Headphones. I'd like it to default to sending output to Line Out. How do I do that?
I can manually change where the output is current sent as follows: launch the Pulseaudio Volume Control application, go to the Output Devices tab, and next to Port, select the Line Out option instead of Headphones. However, I have to do this after each time I boot the machine -- after a reboot, Pulseaudio resets itself back to Headphones. That's a bit annoying. How do I make my selection stick and persist across reboots?
Here's a screenshot of how the Volume Control application looks after a reboot, with Headphones selected:
If I click on the chooser next to Port, I get the following two options:
Selecting Line Out makes sound work. (Notice that both Headphones and Line Out are marked as "unplugged", but actually I do have something plugged into the Line Out port.)
Comments: I'm not looking for a way to change the default output device. I have only one sound card.
pacmd list-sinks shows only one sink. Therefore,
pacmd set-default-sink is not helpful. (This doesn't help either.) Here what I need to set is the "Port", not the output device. If it's relevant, I'm using Fedora 20 and pulseaudio-5.0-25.fc21.x86_64.
