When I open alsamixer I can regain sound on my headphone by unmuting the speaker channel and increasing the volume on the volume channel. However each time that I unplug my headphone I need to redo this. So it looks like, in contradiction to how the software is programmed and users understand, the headphone and speaker channels work in serial for headphone output instead of parallel. Because this used to work for years (at least since Ubuntu 12.04, I used them all), this bug is introduced in the lastest release (15.04). I also filed this bug in the alsamixer package, but afterwards I realised that I probably have filed it at the wrong spot.
