Testing is good . This fix will be checked into GIT next time I reboot the laptop.  It fixes the "This format doesn't support audio" error message when using non-ffmpeg Audio Ogg encoder and allows for modifying input parameters.

was about to suggest to try plain audio encoding via our own vorbis encoder but recognized settings were not working.

Hopefully attached patch fixes audio-only ogg native encoding param dialog.

Can you try it out?
