No Sound from Chromecast to Receiver
I received a Chromecast device for Christmas this year! I was so excited to turn my Samsung HD television into a smart TV but I immediately ran into issues with getting no sound from receiver when using Chromecast. I was getting sound out of my TV speaker but I really wanted to play my Netflix movies or YouTube videos or anything else using my Chrome browser over my surround sound speakers attached to my audio receiver. After about an hour of adjusting settings on my Onkyo AV Receiver and another hour or so of research on the Internet, I found a solution with the help of a co-worker!
Why is a computer geek blogging about Chromecast, HDMI and AV equipment? I decided to post my experience because I think it will help a lot of people who are completely intimidated when it comes to audio visual setup and configuration like I am. Besides, Chromecast is a really cool technology.
First, it will help to describe, in detail, what my setup at home is like. I’m going to refer to Chromecast as (CC) from here on out.
TV to AV Receiver Connection
HDMI cable plugged into HDMI-In jack on back of TV going to HDMI-Out jack on back of AV Receiver.
Digital Optical Cable plugged into Digital Audio Out (Optical) jack on back of TV going to Digital-In (Optical) jack on back of Receiver.
Therefore, I have only 1 HDMI cable and one Digital Audio Optical cable plugged into my TV. The only other thing plugged into my Samsung TV is the CC device which I have plugged into the USB port. This is really nice since the USB port powers the CC device. If I didn’t have a USB port on the TV, then I would need to plug the CC device into a power outlet with the power adapter which comes with the CC.
I read many articles regarding how I needed to connect my CC device to my receiver using the included HDMI adapter. I also read articles on how this would not work with my setup because my receiver and TV do not support ARC (Audio Return Channel). My equipment is approximately 3 to 4 years old so it did not come with HDMI 1.4/1.4a which is the version of HDMI with the ARC specification. However, all I needed to do was connect a Digital Optical Cable from my TV to the Digital-In jack in my receiver. My TV is mounted above the fireplace and my audio equipment is hidden in a cabinet so I needed an extra long Digital Optical Cable cable and snaked it through. Just a note, if you go to buy an optical cable at a brick and mortar store like Best Buy or Radio Shack, you will pay triple or more than buying it on Amazon.
When I first connected the AV Receiver to my TV, I did it the way most people do (I think). Like I stated above, I connected one HDMI cable from the main HDMI-In jack on the back of the TV to the HDMI-Out jack on the back of the AV Receiver. Then, I connected the rest of my equipment like a DVD Player, Cable/Satellite box and CD player to the remaining HDMI or coaxial jacks on the back of the AV receiver. Then on the AV Receiver, I configured the audio settings for the DVD Player to the Digital Audio Optical jack, the CD player to the coaxial jacks and the Cable/Satellite to the other Digital Audio Optical jack.
I know, this looks and sounds very confusing. I’m confused just writing it! But it all worked for years until I wanted my CC device to play over the audio system through the AV Receiver. I can’t believe how much simpler the whole connection is now that I connected a Digital Audio Optical cable from my TV to the AV Receiver. All I had to do was change the audio settings on my Onkyo receiver for the DVD and Cable/Satellite jacks to play audio through the Digital Audio Optical jack that is connected to the TV.
Chromecast is pretty cool technology. I can stream video or pictures directly from any wireless device, including my smart phone, to my TV. The quality is high definition and of course, the audio is now playing through my wonderful Onkyo speakers.
I hope this helps someone. If so, feel free to leave a comment!
