If you replace directsoundsink with "wavenc ! filesink
location=output.wav" and open the file in an audio editor (e.g.
Audacity) you can check if there is something wrong with interleave.
I tried your pipeline with 1.10.4 on linux and the produced audio
data seems to be OK here, so I don't think interleave is the problem.
It could be directsoundsink (try using the mixer to mute the right and
left channel maybe), or the problem could even be in the analog part of
the system.
When saying PEBCAC (Problem Exists Between Chair And Computer)
sometimes it is the user but sometimes it's just the cables. :)
Let us know if you figure out what is actually causing the issue.
