More investigation, added a few clues to the debug MSGT_ things:

For some reason line 114 of ad_ffmpeg.c is getting a value of 8000
despite mplayer.c already having a decent value for sh_audio->i_bps.
(I had a trace for line 122 in ad_ffmpeg.c, too, which did not spring.)
Ok... now either I can chase down why lavc_context->bit_rate is
wrong, or we can wrap lines 114 & 122 with, say, an
if(!sh_audio->i_bps)
or similar, to not change our good i_bps ATM?
But this could mess with other formats?
Thanks for helping with this...
