+I had the same problem with a nvidia sound chip. The solution for me:
+Right click on the kmix symbol (in KDE) and select "Main channel
+selection" (or similar in English). Then I see a small dialogue where
+I can change between "Internal Audio Analog Stereo" and "High
+Definition Audio Controller (HDMI)". Selecting "internal" solved the
+problem.
