Comment:
The main issue is that afaict WMP does not support 96kHz aac, workaround
is to use {{{-ar 48k}}}.
The input sample uses SBR (which kind of doubles the sample rate), WMP is
definitely playing it, no matter how often I remux it (or to which
container). Reencoding with FFmpeg leads to 96kHz (without SBR) which
isn't played by WMP.
One issue I see is that FFmpeg doesn't show that the sample uses SBR, the
other issues are the warnings that are a regression since
