MP4 Pass Through No Audio

[MediaGuy]

Hi cannot seem to get any audio from ripping Dolby Vision 4k discs. The video is fine but there not any audio track. This is happening everything I do it.

I am choosing MP4.Passthrough and then under Audio I choose Same as Source and under Dolby Vision I choose Copy Dolby Vision. Is there a reason that that the audio track would not be included in the rip?

Thanks
