I am hoping to work around the fact that my normal headphone jack is broken and doesn't pick up headphones very well at all. My thought is that it might be possible to use the surround ports on the back instead: I have found out here that the line out port is used for front speakers in surround systems so I thought it might be the best port to use for the headphone hardware.
I'm assuming that alsa has a specific profile set for this port that is not intended for use with headphones, so I am wondering whether there is a way, under Arch Linux, to take the configuration for the front headphone port and apply it to line out, as I won't be using surround audio systems at all.
I am using pulseaudio to manage my sound and I would like to find out whether this can be done using it. If not, I would like to know how to configure alsa to reach my goal, using the
pulseaudio-alsa plugin to make ALSA work with pulse.
