Get Dolby Atmos sound file from Onair live stream

[Trainfire]

Hello all!

I have managed to rip a live show (or vod) of a concert I really want to keep on my server, but since I use Windows to do this on I only manage to get Stereo audio file for it.
The show is available with Dolby Atmos, but it automatically downscale to Stereo since that's the only audio device I have on my pc.
Is there a way to "trick" the stream into thinking I have Dolby so I can pull that file instead?

I had a thought that if I was able to stream it with Dolby Atmos via HDMI to my reciever, then that should make the Atmos file available I would assume? However I am struggling getting it to play through Microsoft Edge with Atmos. (Seems like a Edge problem. VLC plays Atmos files just fine)

Hi, Can I ask how you decrypted the Onair rip?
i've been trying with n_m3u8dl-re and what I assume is a valid key from the wideine decryptor, but my outputs are still garbled.
