When I rip a BR with Makemkv and then try to play it through DLNA through my Onkyo system there is no sound.

If I used Handbrake to reduce the size then the audio works fine.

Anybody have this problem?

Most likely, the Onkyo doesn't support the audio format you have selected. Running it through handbrake converts the default track to something the Onkyo does understand.
