I bought this one couple of days ago. The connection with my TV is OK but after about 5 minutes the transmitter indicator starts to blink and lose the audio feed. After reading the manual I find that's normal if there is no audio feed, mute, which is not my case. The manual also suggests to increase the volume of the tv and/or the receiver which I did and the problem stil exists. I also switch between the three channels in the back of the transmitter without any change.
