We just purchased a new Roku Express+. We have the HDMI hooked directly to our TV, sound muted. The composite a/v cable is connected to our audio receiver.
With this setup, we can watch HD video, while at the same time, listen to the audio as it is going through our sound system. However, the audio eventually cuts out. Only replugging the HDMI cable or restarting the Roku will restore the audio, and then, only temporarily, until it cuts out again.
The Roku works normally when viewing/listening, either only through composite A/V, or only via HDMI (TV unmuted).
Any advice for how to make my preferred setup for audio work with HDMI video, without purchasing an additional HTML audio extractor?
