Extracting Audio files from Assassin's Creed Valhalla

[Karimmusa]

Hey guys,
I've been trying for atleast two days with this game and I can't for the life of me convert the files extracted from the pck file
So I extracted the music for Assassin's Creed Origins simply by using WWise unpacker and it worked like a charm.

For this game it's a pck file and when extracting the files I'm met with .WAV files
so for the music.pck file it gives me 691 file, only 122 get converted by wwise to ogg files.
The rest of the files are simply not convertable WAV files.
I either get
Parse error: expected 0x42 fmt if vorb Messing
or
parse error: unknown chunk type
Depending on the tool

I tried using a wwise_ima_adpcm tool but I cannot seem to convert the files to wem in the first place
Here are some sample files

and here is the PCK file I'm trying to extract

Can anyone atleast confirm if they are corrupted files or something?

Also I posted on Github in this thread
https://github.com/vgmstream/vgmstream/issues/762
basically they are Wwise Opus files and cannot be played at all atm.

Anyone can help with this please?
Thanks in advance
