It's because x264enc by default consumes up to 3 seconds of video
before outputting anything, but there's less queuing than that on the
other branches.

Try using x264enc tune=zerolatency (there are better options to tweak
this, but this is the simplest) or use queue max-size-time=0 max-size-
bytes=0 max-size-buffers=0 in your audio branch.
