Problem muxing video with 5.1 audio after dl

[monk87]

I have a problem downloading video with 6CH audio.
Command i use:

N_m3u8DL-RE.exe https://r.cdn-ncplus.pl/vod/store01/CAP_21055311/_/hd4-hssdrm02.ism/Manifest -sv res=\"x1080\" -sa codec=\"*EC-3\":lang=\"pol\" --key 65347ed53e174054a74c76c549f901b6:5a44539232d3bdd748d42676f6c7f0c5 -M format=mp4

but there's an error like this and file is without audio track:

17:29:34.762 INFO : Decrypting using MP4DECRYPT...

also tried manual download, decrypt and ffmpeg mux but it gives me:

any idea how this can be fixed?

on the old manifest you won't download 5.1 audio because 5.1 audio has a different key than what you have

old manifest (ism/Manifest) | new (.mpd)
