I am really a Ubuntu user who is trying openSUSE, and so far, after initiall glitches, things seem to work except for the occasional sound problems.
Instead of playing CLI sound test (which looks obscure and difficult to remember), I click on Test buttons either on Gstreamer Properties or on Sound Preferances window.
If I hear a tone, I know the sound works.
The following scenario always worked for me for totem:
1. On Gstreamer set audio to ALSA (everywhere).
2. alsa-init
I do not know what is causing ALSA to fail, there must be some application that does that. It never happened to me on Ubuntu. When I look at /var/log/messages I see a lot of alsa related errors:
