[Solved] Roku 3 no audio on HDMI

keepitsimpleengineer · Fri Jun 21, 2013 10:28 am

So I buy a Roku 3 in April, receive it and test on my Samsung flat-screen TV. It works for a while then suddenly video without audio. After swapping around HDMI cables and HDMI input ports, I find that the problem is the audio on the HDMI port the Roku 3 was plugged into (#2). Grumble. But since I only need one because I would be running all HDMI inputs through the Pioneer receiver, I could live with it.

Last night, after enjoying Netflix on Roku 3, suddenly video with no audio. Same thing, the HDMI port on the receiver no longer passes audio – just as in the Samsung flat-screen.

I test the HDMI-in port on the receiver the Roku 3 was using, and there was video but no audio using my DVR and Blu-ray player HDMI inputs. Also, the Roku produces audio and video when plugged into another HDMI-in port on the receiver.

It seems unlikely that any device outputting audio and video could kill just the audio and leave the video for a HDMI-in port, but I have no other explanation.

If this is the case what to do? The Roku player has damaged a very expensive flat-screen and a HDMI receiver?

Just to give you little more information, the Roku doesn't decode or amplify any audio. It just passes it through at line level to the TV or receiver to decode.

I don't see how the HDMI on the Roku could cause an issue or failure of the HDMI on another component/TV. It's far more likely that the ports could already have been bad/damaged, and plugging in and out caused the actual issue.

My first stop would be to contact CS. I'd probably contact the CS for the TV/AVR as well, just to cover the bases.

I don't see how either. The Roku 3 and DVR are on with internet connection 24/7. The receiver and TV are turned off and on as needed. Receiver gets audio from TV via optical
TV -optical-> Receiver

However, the Roku 3 is the only common device in both occurances. I don't see how plugging in/out because one day it worked and the next day it didn't - without any changes in the cables and ports - the Roku 3 stays in a cupboard with the receiver.

Before: audio and video via the HDMI in port far all devices. After: Only video no audio on the same port for all devices. While the Roku 3 device via HDMI to a different port works both audio and video. The Roku 3 is on with internet connection 24/7.

In the meanwhile, I'm afraid to use the Roku lest it smite another HDMI in port. I could use some help.

Roku CS unresponsive, Pioneer emailed, Samsung in the works.

When you do get in touch with CS, be sure to note your ticket number. I'll be able to follow-up with CS management afterwards.

Receiver gets audio from TV via optical
TV -optical-> Receiver

OP. Do you have Netflix set to stereo or 5.1 audio?
Netflix 5.1 is DD+, which can't be passed via optical.

I thought you listed this in your first post:

There was a long thread about audio issues with the 522 so I think that's unrelated.

If you have the Roku player set to output 5.1 audio but have it connected to the TV, you need to change it to stereo because page 11 of your TV's manual says that:

When the source is a digital component such as a DVD / Blu-ray player / cable box / STB 
(Set-Top-Box) satellite receiver and is connected to the TV via HDMI, only 2 CH audio will be heard from the 
amplifier or DVD home theater. If you want to hear 5.1 CH audio, connect the digital audio out jack from your 
DVD / Blu-ray player / cable box / STB satellite receiver directly to an amplifier or home theater.

If you set the Roku player to output stereo and connect it to your TV or receiver, can you get audio on either?

Setup is [Roku3,Blu-ray,and DVR]}-HDMI->Receiver-HDMI->TV
for watching TV, it's [TV]}-Optical->Receiver

No audio with any setting from Roku3 when connected to the receiver on Roku3's original HDMI in port. When connected to another HDMI in port (i.e. the original in port for the DVR or Blu-ray) on the receiver, full video and audio.

The DVR and Blu-ray show the same behavior.

Netflix is set to 5.1 DD+, which the VSX-520-K handles.

After I got the system sorted (by replacing the receiver that claimed to support DD+ with one that actually did) the setup worked very nicely.

Then a few days ago it just stopped doing audio.

The Roku3 and receiver, DVR and Blu-ray are in a cupboard, and access to cabling requires a trip to the laundry room, removing a cork-board and opening a panel which is the back of the cupboard. Thus I'm pretty sure the cabling was not changed.

True for the most part, actually it converts the TCP/IP packets to encoded audio/video for HDMI out. The receiver either optionally passes along the audio to its HDMI out, or it decodes/processes the audio and drives the speakers. In my case it is the latter, and the speakers on the TV are disabled.

Can you double-check if your receiver is set to output audio to the TV or speakers? I think it's called AMP/THRU on Pioneer sets, not 100% sure.

You are correct. And it is set to AMP.
