The Problem still exists on my machine .. :-( It seems that some (k)ubuntu updates seem to disable the IEC958 IN Monitor Switch on the sound configuration. After much trying with alsamixer this seems to be a solution. The sound works proper for a while and a few days ago the silence came back. And now after reenabling IEC IN Monitor settings in KMix it works again. Strange ...
