audio question for those who use Davinci Resolve...

So in the past, I ripped AOTC from my blu-ray, used handbrake, and through some finagling, got it to import all the channels separately into Davinci Resolve. I’ve wanted to do the same with the other prequels.
So, as far as I can tell, I’ve done everything exactly the same way - the video imports fine, but no audio.
I go to Clip Attributes and there’s nothing! No audio available. But I know for a fact the audio IS there!
Anyone got any ideas as to why?
Or is there some software where I can rip just the audio, that way, I could just sync it with the video in Davinci?
