I played around a bit with recording the HDMI-In on a Mutant HD2400.
A recording is made. And plays back. However no sound as reported above.
So, I started to investigate the recording.
The picture is being stored as 1280x720. No surprise here.
The audio is a different matter.
Gstreamer reports an audio track as AAC
extplayer3 reports the audio track as LPCM
Sending the file through mediainfo on the PC give this report:

The audio is not detected.
Tried to convert the .ts file to an mkv file, but MKVtoolnix does not recognize the file.
Tried to recode the file with ffmpeg, No problem with the picture, but the sound is either seen as AAC or A-DTS.
The results is again a sound track which is silence.
So not much of a success there.
Searched the net to extract the audio stream out of a .ts file. (To examine the audio stream separately) but I could not find how to do this.
Does somebody know how to do this?
