So for me - TV Philips 32PFL5605H and Beamer LG PA1000 - no sound, but it is only transmitted image. :( When Beamer "Telefunken DLP400" went not ... Now I do not know if the adapter will only work with certain devices, or it is broken ???
I close it to my ThinkPad T420s (Win 8.1) and use this "AmazonBasics High-Speed HDMI cable".
