[Furkan Alaca <falaca@xxxxxxxxx>]

Public bug reported:

This is a regression from Ubuntu 14.04 (I have not tested 14.10).

Headphones which were already plugged in prior to a suspend/resume cycle
or a shutdown/reboot are not detected after a power-on (i.e.,
"Headphones: Built-in Audio" is absent from the "Output" tab in the
Sound Settings). Unplugging the headphones and plugging them back in
results in the headphones being detected and automatically selected.

I used the ubuntu-bug tool to submit this bug report after a fresh boot,
and after going through the troubleshooting steps (which unsuccessfully
attempted to play some tones through the headphone jack), "Headphones"
showed up in the Output tab (without me having to unplug them and plug
them in again), but was not automatically selected ("Line Out" is
selected by default). Manually selecting "Headphones" succeeded in
enabling sound on the headphones. So it appears that perhaps pulseaudio
does not automatically check for the presence of headphones upon boot or
resume from suspend (or maybe it does, but the hardware isn't ready to
respond at the time).
