The card doesn't seem to have a separate headphone jack itself[1], so I suppose the "Headphone" mixer element controls the front panel output volume, if you have such thing hooked to the card. I think the kernel should create a jack element for the back panel output (at least a phantom jack, if proper jack detection can't be implemented). That would allow PulseAudio to distinguish between the back and front panel outputs. As a workaround, I think removing the contents of /usr/share/pulseaudio/alsa-mixer/paths/analog-output- headphones.conf would make the volume control work again (just delete the contents, not the file itself). The reason why this worked before version 7.1 is that your "Master" volume element has more than 2 channels, which PulseAudio couldn't handle, so the headphone path (which includes the "Master" element) was disabled. PulseAudio still can't handle volume elements with more than 2 channels, but as of 7.1, such elements are just ignored, so they don't disable the whole path.
