I will test now.  Am testing libsvtav1 and ffmpeg.C aspect patch at the same time.  If libsvtav1 works OK on Ubuntu 16 and 32-bit Debian 9.1, would it be advisable to always build it in instead of having to add it to the configure line via --enable-libsvtav1 ?

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?
