I've got 2 sound devices on my system:
1. HDMI/DisplayPort2
2. HDMI/DisplayPort

As I resume from suspend, the right panel of the system/sound becomes: settings for: Analog headphones (however on the left panel there's no such device)

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

This may be a bug in Pulseaudio introduced in version 8 - at least it was in my case. The issue is fixed in the newest release of Pulseaudio (Automatic routing improvements) - https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/9.0/.

*It did not appear in Ubuntu 14.04 (which uses version 4) and does appear in 16.10 (which uses version 8).
*I could fix it through brute force be making the *-default-sink file in ~/.config/pulse ro.
*I fixed it through the temporary fix as outlined in this post - https://lists.freedesktop.org/archives/pulseaudio-bugs/2016-February/010460.html. Please note that this may introduce other regressions. Read the entire post to find out what. The regressions should not affect the vast majority of users.

Hope this helps.
