Description

I recently found that tvh worngly reports the type and sample rate of incoming AAC stream.
As stated in the log, it says the audio is LATM and 96KHz

but it's actually ADTS and 48KHz. (reported by MediaInfo, agrees with VLC, PotPlayer, and VideoRedo)

Delay relative to video                  : -176 ms

Transcoding the video isn't working too; resulting as no audio stream, both on recording or watching (streaming).
Only I can hear and record the audio when pass profile has been chosen.
I'll attach both the passed and transcoded recordings soon.
