Try an USB-2 port, some USB-3 bridges don't pair well with comtrue interfaces. I can attest, no problem at all playing DSD up to 256 on Windows (foobar, roon, etc. , DSD512 is tricky. Comtrue USB Audio Device is for S9 drivers, S9 Pro shows up indeed as SXW UAD. S9 Pro supports S9 drivers, the opposite not.I finally tried some DSD 64's from various sources, they ALL stutter and sputter like crazy on my S9 Pro (Foobar2000 and Audrivana). These same files play fine on my S8 and a FiiO. Crap.
Edit: someone mentioned the "Comtrue USB Audio Device" for ASIO so I went and found that driver. Oddly it shows up as "SXW UAD ASIO" in the device list for me, but whatever.
Hidizs sent me v1.1 firmware but it didn't help on my HP Spectre x360. I tried it on my MacBook Pro 14" and my Samsung Note 20 Ultra (USB Audio Play Pro) and guess what? It works fine. So... it's something odd with the HP. I have an S8 and some FiiO DAC's and they have no problem with DSD playback. It's some weird alchemy between the S9 Pro and the HP. :/
I'll see if I have a USB 2 hub still lying around. I thought maybe the USB-A port on this laptop was USB-2, but it's not.Try an USB-2 port, some USB-3 bridges don't pair well with comtrue interfaces.

BTW, the drivers for the S9 Pro are showing up as Comtrue for me. But it does say SXW UAD for ASIO.

I ordered an S9 non-pro from Hidizs US site about a month ago. It was in stock, shockingly, despite the main page saying out of stock, but the product page had 'add to cart' button available. Arrived yesterday. Checked Device Manager, says S9, not S9 Pro. Did I get a unicorn?
Maybe they had a drawer full of them...just for a rainy dayAbout that, I posted somewhere : is AKM back in business ? Looks like it, S9 available again, Lotoo PAW S2 out and using AKM dac...

Hey thanks a ton for this! I have been searching for this for a few days now and you helped me in fixing this issue. I have just one question for you. when the song changes from 192/24 to 96/24, shouldn't the colour code on Hidizs DAC change to green from purple? I am listening on Apple Music on my Macbook Air. Going by your steps, I changed the MIDI set up and now the colour on the DAC is purple permanently irrespective of the resolution of the song. I am simply trying to understand if that should be the case or the colour on DAC change between purple and green depending upon what's the resolution of the music being played. Thanks!Thanks! Your info helped solve it. In iOs on my MacBook, went into "Audio MIDA Setup " app and changed the output settings which were limited to 16/44. Probably same concept in Windows
macOS will resample all audio to the sample rate selected in the MIDI setup.Hey thanks a ton for this! I have been searching for this for a few days now and you helped me in fixing this issue.

Thank you! One follow up: Should I leave sample rate in the MIDI setup at 192/24 or 96/24? Is there's an issue if 96/42 audio is played if the sample rate on Mac is set at 192/24? I mean it will upsample but will it make the music sound bad?macOS will resample all audio to the sample rate selected in the MIDI setup.
I'm not sure if Bit-perfect playback is even possible in macOS.
On Windows you can use Wasapi exclusive or ASIO to play all your songs at their native sample rate.
On Android you can use USB Audio Player Pro or Hiby Music to do the same.
Yes, it's definitely possible largely dependent on the player and DACI'm not sure if Bit-perfect playback is even possible in macOS
This is correct, macOS will resample and does not (by default) dynamically change the output rates based on the source unless your player software (and I believe the DAC also) supports this, as I understand this is referred to as 'Exclusive Mode'. I know the S9 does support this as I have one and this works fine for me using Roon, I get blue light on 192 files and green on less than that. Also tested this successfully on DSD files using Pine Player Audio.macOS will resample all audio to the sample rate selected in the MIDI setup.
Yes, you can set this at 192/24 on MIDI a and let macOS upsample all files prior to sending to the DAC, providing your Mac has enough compute resources to manage this. According to tests performed by @Archimago here you can expect this to work perfectly well without measurable impact to the source signal. Note the tests were done on quite an old version of macOS (Yosemite), I can only assume this remains the case for more recent OS's (read versions of mac's CoreAudio)Thank you!

Whose sensitivity measurement would you like me to use?Can someone tell me how to calculate the maximum volume, when I plug in headphones (ballanced) with the following data?
The preamp is at -7db (Harman target).

If Amir test the S9Pro with his Neurochrome load box, like this:I understand.
Then the best comparison I can use is the Topping nx4 .
I connected it to the Utopia a few months ago. We know its performance compared to the S9. As far as I can remember, the volume was enough for me.
But in the end that doesn't solve my question. Afterwards I ordered the s9pro as a precaution.
