Comment:

 Hi,

 this is expected since the segment will use by default the video as
 reference stream.
 As a workaround, you can use {{{reference_stream a}}} to force audio as
 reference. I'm not sure if we should change the default to ignore video
 streams which are attachments, comments are welcome.
