Cannot decode xHE-AAC with audiotoolbox (aac_at) on Mac OS Monterey

[death]

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):

Bad output 2 (Mac OS Monterey virtual machine, Intel):

Example file that I used to produce the above logs:

Here are two patches:

​https://gist.github.com/kode54/5c5005be2365ef7c4592f9cbccb898bc

The first patch fixes the bug, the second is just a quality of life enhancement to output all the formats that are likely to be float internally as floating point, instead of outputting as int32 or int16.

Applied Christopher's patches, problem confirmed fixed.

Please merge these patches with mainline FFmpeg.

Thanks.

I have also submitted these two patches separately to the ffmpeg-devel mailing list.

Fixed in 944b8c96c90ae050606e638f77a15d6292209b91.

What about float patches?
