I ve bought this HDMI adapter for my Galaxy Note 10.1. J well get the picture on my tv but impossible to get sound. J have tried different HDMI cables, without success. An internet search shows that I'm not the only one to have this concern, but that no solution seems to exist. I put 2 stars in terms of view content not requiring his (correct image quality), but avoid product for those who want to watch videos or Youtube!
