Asus Z87-Pro (onboard Sound ALC1150), Ubuntu 15.10, Gnome3.
$ cat /proc/asound/cards 0 [HDMI ]: HDA-Intel - HDA Intel HDMI HDA Intel HDMI at 0xefd34000 irq 34 1 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xefd30000 irq 33
Gnome sound settings and pulseaudio (e.g. pavucontrol) only offer to use HDMI output (sound card 0). pavucontrol -> configuration shows two internal devices, first offering some HDMI output options, second card listing some analog output options (2.0, 5.1,... + many other options) but all those lines end with "(unplugged)".
Manually selecting the card works, the following command is working as it should, I hear the voice from the connected speakers.
aplay -c1 whatever.wav
So I assume the speakers are connected as they should and pulseaudio's jack detection is broken somehow.
Strange detail: there is one single situation presenting perfect sound: it's the sound when logging off...
Is there any way to override jack detection? All threads found so far handle missing device drivers (i.e. card not recognized at all), renaming devices,...
