Seems that there are some issues with encoding of the file that prevents FFMPEG to correctly detect the audio format at the standard probe size. Increasing the probe size seems to do the trick:
ffmpeg.exe -analyzeduration 5G -i https://teste-etv.espiritismo.tv/437602-1080p.m3u8 Try to reduce keyframe distance to 8 or 5 seconds instead of the actual 12 seconds to increase compatibility and better performance for the playback.
