Title:
Headphones not detected after fresh boot or suspend/resume cycle,
until unplugged and plugged back in
Status in alsa-driver package in Ubuntu:
New
Bug description:
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).
