Hi,
I had the same problem... went into the Roku settings/digital output format/Custom/DTS and turned it on. That fixed it on two different Roku models and two different TV manufacturers.
For those with no audio, I had the same issue.
To fix I just went into Settings-Audio- and switched from "Auto" to Custom and just enabled Dolby (normal) and DTS.
I restarted to make sure it took hold and then opened the app again and have audio now. This is on a Roku Express stick going to TV speakers.
My Roku Express4k doesn't seem to have the same luck though with piping from HDMI to TV to receiver.
Edit- the 4k to the soundbar was solved by changing the TV sound settings (for HDMI ARC to soundbar) to "bitstream" from PCM. After that change I had audio on that as well.
Mine still doesnt work
@Wchowe you need to provide some additional information. What model Roku device do you have? What model HDHR device do you have? Is you Roku connected to an AVR, or directly to a TV and using the TV speakers?
Are you watching an ATSC 3.0 channel (this is the next gen of digital TV, and the channel number is likely above 100 (mine start at 104). ATSC 3.0 is only available on the HDRomeRun Flex 4K tuner to my knowledge. But ATSC 3.0 uses AC-4 as the audio codec, and the only Roku players that can decode that is the 4800/4802 Ultra. Any other Roku device is not going to have audio for ATSC 3.0 stations.
I am having trouble getting sound from my HD Homerun using my Roku stick. Would like to know how to fix this. I get sound from every other streaming channel.
