That last character is an L, not a 1, so it's presumably referring to Video4Linux, which is a set of kernel drivers for video hardware. The sequence seems to suggest that v4l isn't quite working right and can't get the audio feed. kaffeine doesn't link v4l itself, but picks it up through xine-lib. xine-lib may be linking it directly or picking it up through ffmpeg, depending on how your distro has it set up. The presence of "avcodec" in the trace suggests ffmpeg's involvement. So I'd start at the kernel level, verify that the correct drivers are available and being attached to the correct devices, then move upward through ffmpeg and xine-lib. (If VLC, which uses libmpeg2 for mpeg2 decoding, happens to work, that would practically be a smoking gun pointing at ffmpeg or xine.) E.
