Just updated from 15.04 to 15.10 and since my system has come up this morning, I can't get any sound from the headphones. I get sound from the internal speakers and the speakers get muted as soon as I plug in my headphones.
The weird thing is that if I reboot into Windows, I get exactly the same behaviour. I can get the Windows sound back to working by completely powering down the system (reboot is not enough). Once I reboot into Kubuntu, however, it's broken again (also for Windows).
The system is a Thinkpad T440p with a Realtek sound card.
This is what I tried:
1) Have Amarok play a song with no headphones plugged in
2) plug headphones in -> internal speakers get muted, no sound from the headphones, but Amarok continues playing
3) pull headphones out -> sound continues from internal speakers
There is no volume control widget in my systray, even though volume control is checked in the systray config.
I then tried the system settings (with headphones plugged):
- Audio volume: Unmuted everything that I could find. Output device for "Built-in analog stereo" is set to "Headphones"; configuration profile is "analog stereo duplex".
- Audio and video: "Buillt-in analog stereo" has highest priority everywhere. In "Audio Hardware setup -> Sound Card", I see two devices. Both go by the name of "Built-in audio". The first one can only be configured to use HDMI profiles; the second one is set to "analog stereo duplex".
Alsamixer:
Shows two Headphone devices, Headphone 0 and Headphone 1. Headphone 0 is unmuted and at full volume; Headphone 1 is unmuted, but fixed to zero volume (there is no cage for a bar above Headphone 1 and the volume cannot be changed).
I found a few old threads that suggested adding "options snd-hda-intel model=thinkpad" to /etc/modprobe.d/alsa-base.conf, but that did not help either.
Another thing that I have noticed: On login, the progress bar on the loading screen runs through quickly, and then the system is stuck on the loading screen for about 10 seconds. Might be totally unrelated, though.
Output of aplay -l:
There are a bunch of errors in .xsession-errors, but nothing that seems related to the problem.

Any idea what's going on here or where I could look for further error messages?
