OK, good. This proves what we need to know, which is your basic sound functions. Everything is simple configuration hiccups that you have encountered because of a lack of familiarity, and its easy to fix. Once you know your way around openSUSE, this sort of thing can be fixed in less than 5 minutes after a fresh install.
Both Amarok and Kaffeine can give one a choice of using either gstreamer or xine as their sound engine. The key thing here is openSUSE as packaged by Novell/SuSE-GmbH is typically crippled for proprietary multimedia codecs, and hence one needs to replace the Novell/SuSE-GmbH packaged multimedia applications with their equivalent Packman packaged multimedia applications. You can tell Packman packaged applications by the “pm” in the application version number.
I recommend you follow caf4926’s guide here to fix the above: Multi-media and Restricted Format Installation Guide - openSUSE Forums
in addition to the apps caf4926 mentions in that guide, also install the packman packaged version of amarok, amarok-packman, amarok-xine , replacing any Novell versions. In amarok, in the menu’s, change the sound engine to use xine.
I myself do NOT like those sounds, hence I’m not one to help you there. BUT if you want help on that, you need to tell those monitoring this thread what desktop you are using, as this tends to be desktop specific. ie the settings for that are different for LXDE, different for Enlightenment, different for Xfce, different for Gnome, different for KDE3, different for KDE4. You need to advise which desktop this does not work.
Also, be certain you have your mixer settings at a good high level for those sounds to work (ie Master, PCM, and speaker controls).
I have no idea what this means. You will need to be 100% precise when quoting such errors if you wish help there. Take a pix of it with your digital camera and post the pix on a site such as imagebam and post here the link so we can see what you are talking about.
