Thanks Raymond. I think I got some interesting results. I ran hdajacksensetest and amixer -c0 contents after a fresh boot (when my headphones were not detected) and ran them again after unplugging and plugging my headphones back in.
hdajacksensetest gave the same result for both tests: Pin 0x24 (Green Line Out, Rear side): present = Yes Pin 0x25 (Black Line Out, Rear side): present = No Pin 0x26 (Orange Line Out, Rear side): present = No Pin 0x27 (Grey Line Out, Rear side): present = No Pin 0x28 (Green Headphone, Front side): present = Yes Pin 0x29 (Pink Mic, Front side): present = No Pin 0x2a (Blue Line In, Rear side): present = No Pin 0x2b (Pink Mic, Rear side): present = No The amixer output changed after unplugging and plugging the headphones back in. I've attached text files showing the before/after output. ** Attachment added: "Output of "amixer -c0 contents" after (1) a fresh boot, and (2) unplugging and plugging headphones back in" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1442428/+attachment/4372625/+files/amixer_output.tar -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1442428 Title: Headphones not detected after fresh boot or suspend/resume cycle, until unplugged and plugged back in Status in alsa-driver package in Ubuntu: Incomplete 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).
