I’m not sure what I did - I think it started when I installed lmms. When I tried to skype shortly after (first time in the newly installed Opensuse 13.2) with a headset, the microphone didn’t work. When I plugged in the jack for the monitor again, sound was gone too. Pulling that out, I could still hear the computer’s internal speaker, which now is off, too.
I fiddled with Veromix settings (switching a KDE output engine and MPris2 on and off) and the audio settings in YaST. At the moment, the two sound devices have been deleted and undergone the short automatic reinstall. (They are called WrestlerHDMI Audio (Radeon HD 6250/6310) and SBx00 Azalia (Intel HD, neither of which appears on the list of addable devices.)
Like you, I am not too sure where to start looking wrt specific recommendations to fix the problem. For me, the best way is to obtain some more information on the sound configuration of your PC. To do this, could you open a konsole/terminal, with your PC still connected to the internet, and as a regular user, send the following command in the konsole/terminal:
/usr/sbin/alsa-info.sh
and select the SHARE/UPLOAD. Don’t bother updating if asked, the update is not at this point in the diagnosis important. After the script completes, it will upload the configuration information to an alsa website, and it will provide in the konsole/xterm the web-address/URL where the script information was uploaded. Please post here the URL/web-address provided.
That will have all sorts of information wrt sound card status, pulse, mixer configuration … etc … and from that it may be possible for me to provide a good and helpful recommendation.
unfortunately, the script only returned an empty space. I saved the output locally and saw that it is a bit of a mouthful. I’m quoting here the short part that is concerned with playback and recording.

I really need the entire script output. But from the little you provided, I can see your HDMI device is card-0. By default all sound is output to card-0. In such a case, you need to tune pulse audio volume control (using pavucontrol) to send sound, at an application basis, to card-1. The same is possibly true for the mic wrt tuning to record from card-1 (and not a non-existent card-0 recording function).
with respect to the sound playback, you have 4 to 5 problems !
(1) sound is muted in Master - you need to unmute it.
(2) sound is muted in Headphones - if you plan to use headphones, you need to unmute it
(3) sound is muted in Speaker - you need to unmute it
(4) sound is muted in PCM - you need to unmute it
(5) your analogue sound device is card-1. By default sound goes to card-0, which is HDMI. So assuming you are not using HDMI, then you need to use the application pavucontrol to select eaach applicaiton to send sound to card-1, or you need to reverse the order of the sound devices. I can tell the first for observations from here:

Now for the Microphone, you have as a minium 3 problems:
(1) “Mic” has 0% play back and is OFF guaranteeing no sound capture possible with your mic.
(2) “Mic Boost” is a 0% making any sound capture very difficult. I recommend a value of around 65%
(3) “Capture” is at 0% capture and is OFF guaranteeing no sound capture possible with any device
I also note automute set to Line Out+Speaker which could also be a problem < not sure > . You could try disabling that.
