Blu-ray player downscaling?

Hey everyone,

I just upgraded my blu-ray player to the Panasonic UB-420 with the twin HDMI ports.  I had the 150 and was able to get Dolby Atmos, but for some reason I can’t get it now and it seems the sound is being downscaled.  I have an LG UN9000 tv, and no settings on that have changed, and the Beam (gen 2) is connected to the eArc with the pass-through setting on the tv.  Does anyone know the settings i need from the blu-ray player and which port the audio HDMI cable should be in to get Dolby Atmos/Digital and multichannel PCM sound like I had with the previous player?  Any assistance appreciated. 

Thanks,

I should clarify: that audio cutting out and being spotty only happens w/Atmos, not DTS.

Is the HDMI Input Audio Format setting on the TV set to Bitstream on all of the used HDMI ports?

Try using a different HDMI cable with the single cable connection.

Ok, I tried a new, higher speed HDMI cable and i’m still getting this same issue with Dolby audio.  I used it as the single connection for audio and video and the issue still isn’t fixed.  i also tried putting this new cable into the Beam and connecting it to the eArc port on the tv and it did the same thing.  i’m really at a loss here, is this just a setting i’m missing, or am i just going to have to suffer with this sound issue until i can add another component (receiver?) to my home theater setup?  it’s so frustrating.

And all of the HDMI inputs on the TV are set to Bitstream, and the dolby audio setting on the blu-ray player is set to Bitstream as well.

Can you please post photos of the HDMI cables connected to the back of the Blu-ray player and TV and post a screenshot of the current Digital Audio Output settings on the UB420?
