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
