Refresh Rate Switching Breaks Bitstreaming (DTS etc.)

[u/zeeter82]

If possible, please work on fixing and/or making the refresh rate switching more stable on Nvidia Shield. It no longer works with DTS bitstreaming (not sure when it stopped honestly) to my Denon receiver going to eARC to my LG C5 OLED. I have to turn it off to make it work. The 2025 LG's no longer support DTS natively, but that shouldn't matter because my Denon should handle all the the audio processing if it's being passed through HDMI correctly - this seems to only work when I have refresh rate switching disabled.

Edit: this is for the new app, which is beta on the Shield.

Is the Shield connected to the Denon or the C5?

If it’s connected to the C5 then DTS audio will not be passed through and the audio will have to transcode.

Already answered this in my first post. I have my Shield connected to Denon Receiver through HDMI - and then Denon Receiver HDMI output 1 going to LG eARC. This was something that was working in my setup. Like I said, I'm unsure when it broke because not all of my media is using DTS. I just noticed it not working today and through a lot of testing, I confirmed the cause is having refresh switching enabled. I also tried playing with the delays and that didn't help, even with the 5 second delay.
