Can it do just audio? The photos on Amazon didn't look like there were audio in/out jacks, just HDMI.I do still have the Alto and as stated used it a "handful of times" with no known issues. All times the transmitter was mounted on a light stand and the receiver directly on a remote speaker. I will probably consider selling it though now that the new solution cover audio and video and at better range. I will report back on it's reliability after the upcoming event in October; but my initial test is very promising.
