Audio on Roku Ultra & Apple TV

I have a Roku Ultra to stream video to the TV in my bedroom. I have connected the optical output of the TV to my Loxjie D40 and output to a pair of Genelec powered speakers and subwoofer, using the balanced XLR jacks. The D40 always reports the input as 24-bit/480kHz resolution (i.e. the displays screen reads "480").

I have my old iPad mini 2 connected to the USB input of a Loxje D30 in my dining room. The analog outputs are connected to an Emotiva PT-100 preamp and another pair of Genelec powered speakers through the single-ended RCA jacks. Since upgrading to Amazon Music Unlimited, the D30 reports its input as 24-bit/192kHz resolution (i.e. the displays screen reads "192"). I can't replicate that when I use the Amazon Music app on my Roku in the bedroom, however. It appears that the Roku will only output 24-bit/480kHz (with 24-bit/192kHz aparently reserved for surround sound systems -- which I dislike and will never use). Ditto for my bedroom TV (a Sony 900e).

I recently added an Apple TV to my bedroom system and it sounded like the sound quality improved (though I didn't look at the D40 to confirm whether it read "192"). Unfortunately, I had to get rid of the Apple TV because it was buggy as hell and the last firmware update caused the whole system to act erratically. I spent an entire day on the phone with Sony Tech Support and we now believe that the Bluetooth from the Apple remote was interfering with the Bluetooth in the TV and the D40. (Other devices would randomly turn themseleves off or on, even in the next room. I didn't have to touch the Apple remote. I ultimately had to hide it in a box in a closet in another room to get it to stop. Sony says it actually damaged my TV.)

Any ideas or suggestions? I am happy to toss the Apple TV. I didn't notice much of an improvement in the video quality. Some titles actually looked worse than on the Roku. But the audio definitely sounded better to my ears. I generally like both my Loxjie DACs, but they can sometimes sound a bit harsh in the high end (especially on the D40).

The Apple TV 4K and Roku Ultra do not support Ultra HD(hi-res) from Amazon Music Unlimited. The Amazon Fire TV Cube Gen 3 supports Amazon Music Ultra HD. But, ALL Amazon Music signals will be output at 24/192 with Best Available Sound setting ON and all bets are off if that signal is input into a TV and then sent out from it over optical cable to a DAC.
 
Generalizations are risky, but TV = 48kHz in many circumstances.

I was thinking of connecting a Wiim Ultra through the ARC input and streaming Amazon Unlimited through that, rather than using the Roku app. But if I have to use my iPad with the Wiim, it's not worth it. I mean, what is the point of having a touch screen if you have to use another screen to make it work?
 
does anyone besides me notice clicks/dropouts using the roku ultra? i had a roku express (hd) and never noticed it, then got a 4k tv (lg c3) and a roku express 4k and started hearing it (though not with the roku hd on the 4k tv), then tried the roku ultra and still notice it, but perhaps a bit less. thought it might be from the toslink going into my dac, but it happens when just using the tv speakers as well.

is there a 4k streaming device that is free from this sort of thing?
 
I have the Roku Ultra latest generation.
It is configured to output Dolby Vision and Dolby Atmos to the Tv.
Then the Tv send the audio to the AVR using HDMI 1.4
There is no pop or cut on the audio and sound quality is good.

But I had to change the HDMI input of the Tv because the first one that I used had bandwidth issue with the video.

do you mean you had to change the HDMI cable? or a different HDMI input port?
 
FWIW - I have the latest Roku Ultra and I have never seen the issues you describe when connected with the optical cable (i.e. TV optical output to DAC/Preamp to powered speakers).

However, I have a smaller, older TV connected to a Roku soundbar and I do get random loss of all sound. Usually on startup (which can be remedied by restarting) or when switching between videos on youtube. I am not fond of soundbars or ARC, but then I don't like surround sound either.

I don't use Apple TV any more, since the update that interfered with the Bluetooth on my TV and other devices. (It made them turn off or on randomly or the remote control the wrong device.) Not worth it for me.

I did buy a high speed Hdmi cable but it only improved marginally the issue. It was the Hdmi port of the Tv that was borderline.
Switching to another Tv port and image/sound went back to normal.
