Audio Missing on Ripped ISO Files

Anyone else have missing audio tracks when using Infuse to view a ripped ISO?

I haven’t checked all of them, but two of my Blu-rays that I ripped to ISO are missing any audio track when viewed with Infuse. However, they both play fine, with audio, in PowerDVD 19 & 20.

I should also mention that if I rip these two Blu-rays to MKV, then the audio is present and plays fine in Infuse. That leads me to believe Infuse is having a problem reading ISO files.
