 I'm no longer able to decode xHE-AAC files on Mac OS Monterey using aac_at
 decoder.
 Note that the built-in FFmpeg AAC decoder doesn't support xHE-AAC.
 On previous Mac OS versions, these tracks were only possible to decode by
 explicitly specifying aac_at decoder.

 Good output (Mac OS Catalina):

 Bad output 1 (Mac OS Monterey, ARM64):
 https://www.foobar2000.org/temp/ffmpeg-xheaac/bad.txt

 Bad output 2 (Mac OS Monterey virtual machine, Intel):
 https://www.foobar2000.org/temp/ffmpeg-xheaac/bad2.txt

 Example file that I used to produce the above logs:

 Thanks.
