I'm not sure when the sound ceased on my system but I tried everything I could thing of and got absolutely nothing. I did various yast stuff and also tried the mixer but to no avail. I finally bought a new card and to my surprised everything was just the same. So I tried it in windows and it worked fine. Eventually, I did some googling and discovered this webpage: http://www.linuxquestions.org/questions/history/189255 where on writer DiWi states that, mentioned on the German SuSE mailing list, there is a known problem with the alsa module in the 2.6.x kernels, and that one line needs to be patched. Solution : Install the kernel sources and patch $KERNEL_SRC/sound/pci/ac97/ac97-codec.c old line 174: { 0x83847658, 0xffffffff, "STAC9758/59", patch_sigmatel_stac9758, NULL }, new line 174: { 0x83847658, 0xffffffff, "STAC9758/59", NULL, NULL }, rebuild the modules and install them I've tried it and it worked. I now have sound. I hope this will help someone who has similar problems but it is also a request for someone at SuSE to pass this on to the relevant person and if possible for it fixed in future patch releases. (The webpage is dated from April of this year.) Eddie
