 Here's a live xHE-AAC radio station:

 https://www.maxradio.ca/UHD/MaxRadio/48k/Max.m3u8

 It actually worked with ffmpeg 6.1.2 albeit audio quality was horrible.

 ffmpeg 7.1 just bails out:
 {{{
 Error decoding audio.
 [ffmpeg/audio] aac: AAC USAC Mps212 is not implemented. Update your FFmpeg
 version to the newest one from Git. If the problem still occurs, it means
 that your file has a feature which has not been implemented.
 }}}

 ffmpeg 7.1 also fails to mux it:
 {{{
