I2S over HDMI cable converts the internal signal to differential LVDS, so the range is longer than straight I2S.It is advised it is short, though. Not a couple meters length. I squared S was never intended to cross long lengths of cable.

My Windows 10 is not in English but I think you will understand.I am thus configuring my Windows and I have no problems with latency, asio and Gustard X16.The sound from the computer is now much better.Turning off a lot of unnecessary services and a minimum of background applications make the sound amazing.I use audiophile optimizer and fidelizer.And I manually turn off many services.ASIO bypasses the Windows Audio system entirely, which can yield lower latency. It was really meant for studios and others to connect their DAW (Digital Audio Workstation) to an interface, sound card or other audio hardware. It requires 3rd party (non-Microsoft) hardware drivers and software.
It is possible that DSD512 or PCM768 might work more reliably with ASIO. Also, I can imagine on a PC with lots of junk running in the background (say, a boatload of Windows update and telemetry services) that ASIO might help avoid some buffer underruns. But I don't know firsthand.
One thing ASIO will do: Guarantee bit-perfect. No Windows software volume etc.
I'm personally running 6 meters long HDMI cable as interconnection between rooms without problem.It is advised it is short, though. Not a couple meters length. I squared S was never intended to cross long lengths of cable.
Just to remove anything BluRay player or HDMI related, I dug out an old Denon CD player from circa 1989 that I have not used in 15+ years. It still works apparently, and has a coax output. I don't get any issues with it connected to the X16. In fact is sounds good as I can expect from it. Playing at 44.1KHz. No dropouts, maybe some pop's but not as pronounced and could be the wax in my ears.
Of note, Bluetooth sounds fine. The phone does support MQA. So does the DAC, but not surprising the DAC does not unfold MQA over Bluetooth. In fact, most "master" tracks won't play at all over Bluetooth for some reason.
I have tried PCM setting on the Roku. Settings are pretty much automatic depending on what is connected.
The Roku Ultra does apparently support 24/192 over PCM, but depends on the app. Which... got me to thinking that the HDCP handshake to the TV is what is limiting and the older TV may be causing an issue. Since the TV sends out parameters of what it is, then the Roku will only send that compatible signal. If I had the Roku plugged into an AVR, then the ROKU would detect the parameters of the AVR. And maybe I would not be having these issues. The pops or cutouts might also so be caused by the return signal from the TV. I dunno just guessing.
There is a separate thread for this. I realize this specific product has MQA capabilities and disgusting this attribute is fine here. However, when we start down the MQA rabbit hole please Take those comments and conversation here please.

In order to test what MQA is doing, the author had to publish his own music on Tidal..
Is he a relative of Amir ?
I don't get it a little, if it's called oversampling, why amir graphs shows it doesn't goes up to 24khz? Maybe just because he use measurements cut of 44khz?It is necessary insofar that a modern (delta-sigma) DAC will extrapolate the input data to a much higher rate, so it can output a smooth analog signal. Some explanation here https://www.audiosciencereview.com/...ing-differ-from-over-sampling.3440/post-83318
If you mean how the different oversampling filters differ, there are trade-offs, simply. Slower filters will roll off the last bit of upper frequency, but quite likely only very young people could hear -3dB at 22kHz for example. There's plenty more to read about it if you're really interested... but TL;DR oversampling filter will not make the sound suddenly different, most people will switch filters and hear absolutely zero change.
Just don't put the oversampling OFF, Gustard recommends trying OFF/NOS(no oversampling mode) only when feeding the DAC very high sample rates so that oversampling is not as necessary for a correct output. Otherwise it won't sound very good...
I would really love a dac that oversample my 44/48khz sources to go 96khz, especially with my young ears and planard headphones that do it well.. It the L-fast a oversample to 'fake' hi-res, or it cut until 24khz only like in graphs?
Oh thanks, you are the first one to tell me it does, it's about 2 year i'm biased how to get at least 96khz hi-res bitrate for my Playstation 3 and 4 systems in optical 44khz, turns out with Topping D50 time ago I had hi-res and with X16 i will too, maybe even 384khz sample or more which every filter i choose Nyquist-screamAny modern Delta-Sigma DAC will oversample, including X16 unless you choose its NOS filter. And it will oversample far higher than 96KHz. It's an integral part of their noise shaping and how they reconstruct a proper waveform from digital samples.
And you (not you personally) really shouldn't use the NOS filter unless you perform software upsampling with HQPlayer or similar software. Check Archimago's classic NOS vs. Digital Filtering DACs and admire those ugly waveforms from the NOS DAC.
I think many people haven't given thought to how sparse the samples are when you get close to the Nyquist frequency (1/2 the sample rate): Reconstructing a decent waveform from just 2 samples isn't trivial -- and arguably wasn't accomplished with music until decades after the Nyquist-Shannon theorem came out. But that's a whole other discussion

With Topping D50 a year ago i find differences, i'm 22 and i was using Linear phase fast roll-off, also because i heard it was the most correct by some experts here, but L-phase on Gustard X16 might not be linear-phase fast roll-off..You generally shouldn't worry about oversampling (or upsampling). Modern DAC chips do a great job of reducing noise and distortion and reconstructing the waveform, and oversampling is part of that process. Just worry about getting a bit-perfect digital stream to the DAC.
You can play with the filter choices. You may be able to hear a difference. With ESS chips I generally can (and my hearing is damaged from Meniere's). With AKM chips I can't, although my wife can. The effect on impulse response is most significant, affected by the amount of ringing. As for the speed of the roll-off, you probably won't hear that.
Note that 44kHz is sampling rate. So the rate at which the file is sampled. You are confusing it with the frequency response. 44kHz sampled files does not mean "played frequencies" to 44kHz. A common misconception.I'm a bit confused again, you mentioned 22khz roll-off, so the dac doesn't really oversample 44khz signal to much higher range of played frequencies like 40khz+, instead of usual 22khz?

Yep but your more technical explanation requires proper understanding of Nyquist sampling theoremI edited my post immediately after posting it to avoid that ambiguity. No ultrasonics are going to magically show up in your 44.1Khz file by the DAC's oversampling. It'll be deliberately limited to 22.05Khz by the source. If you're playing a HiRes file, it may contain ultrasonics up to half the sample rate -- but often they don't.
I know. I tried to keep it simple, but evidently I didn't succeedYep but your more technical explanation requires proper understanding of Nyquist sampling theorem
So so so, at the end of the day the dac's oversampling, won't oversample "low res" 44khz or 48khz data in optical, into higher?I edited my post immediately after posting it to avoid that ambiguity.
