I'm trying to convert these vp9 files from Skate It but there's no sound on any of them. I converted with FFmpeg, and tried Virtualdub and they both couldn't find any audio streams. I found some .big files that might contain the audio, but I can't seem to find where they are. I found some .big files and extracted them with QuickBMS, but all it shows is .bin files. There's also a speech.big file, but it looks like it's all the voice lines. Is there any way I could get these working with sound?

As I thought, the audio stream were already inside the VP6 files, just not supported by most standard media players/tools since they were in multichannels (AFAIK they only support stereo EA ADPCM files and also the BIG files is too small so the audio streams definitely aren't there). You can try to demux it with VGMToolbox or VP6 Converter (if you can find it) then convert the audio streams (sng/dat) with vgmstream to wav.
