FWIW, on my laptop running 15.2, alsamixer shows the reaction when a headset is plugged in and out. (sound card = HDA Intel PCH). I am curious to know if you see the same:
In - speaker volume is reduced to 0, headphone volume set to 100. Master is reduced to about 50%. Out - speaker volume is increased to 100, headphone volume set to 0. Master is increased to 100.
No, volumes do not change here.
Looking at alsamixer, tab "Output Devices", er...
pause.
At this moment, it shows "Dummy output" and sound does not work, at all.
That sounds reasonable :-)
I have to run "yast2 sound", delete the card, add it again (edit), automatic quick setup. This happens on almost every reboot (no solution for this, either).
That is weird - is this specific to 15.4? If I run "yast2 sound", I see two devices listed, but both "Not configured". IOW, apparently a yast configuration is not required in order to have sound. In alsamixer, I have two devices - "HDA Intel HDMI", and "HDA Intel PCH".
Now, Looking at alsamixer, tab "Output Devices", I see it shows "CA0110 (Soundblaster X-Fi Xtreme Audio (SB1040 PCI Express) Analog Stereo), set at 41% on port "Line out (plugged in)". Headphones show as unplugged, volume at 18%.
I connect the headphones, and automatically alsamixer shows them as connected, same volume. Line out can be selected, same level as before. But neither output produces sound, despite alsamixer showing that there is audio going out. None show as muted, and clicking the mute icon doesn't change the situation.
I can't help but suspect some configuration conflict/issue - that you need to fiddle with yast whereas I don't, that is odd. Given that my config works without a yast sound config, in your situation I would be tempted to get rid of it and start from there. -- Per Jessen, Zürich (22.5°C)
