You're welcome.
Oh, I forgot to mention "chapter 2" in the manual ;)
When you configure libquicktime add the "--enable-debug":
./configure --enable-debug
that will provide more info

Ok - that's a good start. It's something in how xawtv/streamer is
initializing or writing the audio track.
The audio track handling is something that did change in libquicktime
as I recall.

Happy to be of service.
I think the next steps are to build both streamer and libquicktime
with debug symbol information. For libquicktime that is easy (just
add --enable-debug at ./configure time).
The other thing that can be done is find where streamer is calling
'quicktime_set_audio' and find out if it is setting things up
correctly for what libquicktime is expecting.
