Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review and reply.
You are missing an important connection here, as there is no way for the chromecast audio to get to the surround receiver.You'd need to add a separate optical cable from the digital audio out port on the media unit to the surround receiver, similar to what you did for the cable connection.
I'm talking about from the media receiver, not from the cable box.
You also have to go into the media receiver menu and set the input modes to look for the hdmi input for audio for the chromecast.
Even then though, this still is not likely to work as these old pioneer tvs did not fully support hdmi connectivity and had difficulty with being able to output audio from digital (hdmi) sources.
If this setting doesn't help, you wouldn't be able to use the chromecast in this configuration. Your best option at that point would be to either go with a different streaming device that has an external audio port on it, or to upgrade your receiver to a newer model that supports hdmi. I can give recommendations for either, if necessary.
okay that is fine to start for the physical connection, the receiver needs to be set to the correct input now, and the media receiver needs to be set to accept the hdmi audio and video input both from the same port.
That is the correct setting, thanks for checking, so if that isn't working really the only model that would work for you is the roku ultra, you can get one on amazon here: http://amzn.to/2tXyEC3
this model is necessary because it is the only one with both hdmi and optical, which you'll need to split (hdmi to tv, optical to the receiver).
