#3591: Setting the audio bitrate for the second (or all following) streams does
not work

-------------------------------------+-------------------------------------
When you set the audio bitrate for the second (or all following) audio
streams, that setting is ignored. All audio bitrates are set to the first.
In the following example the audio bitrate for the first audio stream is
set to 128k, the second to 256k.
You will notice the second is also encoded to 128k.
This is the case with any audio codec.
Happens with the latest GIT and point release.
