Playback Issues - Audio/Video & Power

[livetecs]

Hello,
 
I am trying to replace my Shield TV with my Roku Ultra. And facing issues related to audio in both Netflix and Amazon Prime

 My Shield TV audio is very clear and loud. Roku audio is low. And we increase volume, audio becomes very bad.  Both are connected via HDMI port in my Onkyo Receiver. Shield TV audio quality is great. Roku sound is also great but dialogs are not as great as Shield TV and sound is low.
 
I have also tried to set all new volume options

Any suggestion?

I have a Shield, as well as the older version of the Ultra. Both were connected to a Yamaha AVR, and I never encountered any audio issues as you describe. I've dropped Netflix, but use Amazon all the time. I wonder if there's some sort of audio processing enabled on your AVR with the Ultra that wasn't enabled on the Shield, such as one of the hall modes. Those can really mess with the sound sometimes. All of the audio and HDMI settings on my Ultra are set to Auto, and the Yamaha is not using any of the artificial sound modes.

Both are working using the default setting

I will also double check on  this

Here is the manual of my Onkyo Receiver.  There is no such setting in there

Actually, yes it does have some special audio modes. Page 62-63 of the PDF you provided mentions a number of different possible listening modes. Any of those might be altering the audio in a way that is causing the differences you are hearing. For example, the Orchestra or Studio-Mix might be altering the center channel, causing changes in the sound of dialog in that channel. If you have your Roku and Shield connected to different HDMI inputs, different settings might be set, so they aren't being processed the same.
