WD My Cloud... No sound on some movies w/Roku

WD My Cloud… No sound on some movies. Seems like any movie that has “BluRay” in the title has no sound if I’m running this through Roku. I know it’s there and can get sound on these if I use my WD Live. I’d rather use Roku as it’s wired and my WD Live is wireless.

Check if the audio format you are trying to play is compatible with the Roku.
