Shield Pro and Arc Ultra Dolby Sound Briefly Cutting Out

11 replies

I am streaming with a hardwired (1Gb/s) Nvidia Shield Pro passthrough to a TCL 65QM851G TV. My new Sonos Arc Ultra is plugged into the eARC port of the TV and the TV is set to passthrough to the Arc Ultra. I also have a pair of ERA100’s for surrounds. The Sonos gear is connected to a 5G wifi network. The system plays/streams PCM stereo content with no issue but when I stream any type of Dolby content (Dolby Atmos or Dolby Plus 5.1) it plays awesome for about 5 minutes then the sound starts to drop out very briefly about every 1-2 seconds. If I pause the stream for a couple seconds and restart it, the cycle repeats, 5 minutes of awesome sound then the dropouts restart. What can I do to rectify this issue?

Don,

Unfortunately I don't have any 4K streaming services. I'm running a plex server and also putting 4K/Blu Rays into an Xbox and having it passthrough that way. Gaming in atmos on the Xbox has the same issues as well. The TVs internet and codec library doesn't handle plex well. I also believe all streaming services use Dolby Digital as the base coded where the Blu rays will use Dolby True HD and be uncompressed. So the streaming services may work but aren't apples to apples. Maybe I'll try to find a free trial to use and see if that changes anything.

When I have a PC connected and set windows to atmos I have the same issue are these are the common use cases.

Thanks
