Poor sound between WD TV Live Hub and Samsung HT

I recently purchased a Samsung Home Theatre system (HT-E6750W). I linked my WD to the system using a HDMI cable. When playing any form of sound either video or audio it from time cuts out for a second before coming back. The image is not affected. My setting on my WD are:

Video Out: HDMI (auto)

Audio Out: Digital Pass through via HDMI Only

Any ideas of what the issue could be or a solution are greatly appreciated.

All good fixed the issue myself. What I did (for future reference) is just used a better (more expensive) HDMI cable. The settings remained Audio out: Digital Pass through HDMI only
