Laptop Specifications To Play DSD Files
SKY1950:
Hi All, I used mains power to run some tests and now Hi Res 192KHz 24bit Flac plays fine unfortunately the DSD 256 file still buffers, tried different settings in memory but no change, can I change the setting between Native and DoP to test ?

Awesome Donkey:
You might try contacting the device manufacturer and see if the DAC only supports DoP or both DoP and native DSD. If DoP is supported, it *should* work through WASAPI exclusive along with ASIO, assuming your DAC has a ASIO driver available. If ASIO is an option, in MC's Options > Audio > Device settings there should be a Bitstream DSD in DoP option which will enable DoP. Unchecking that box will force native DSD - WASAPI Exclusive on the other hand is DoP only, so that may be worth experimenting with as well.
The DAC's specs aren't very clear about what it supports, but it does mention this...
--- Code: ---Supported DSD Rates:
Windows: DSD64, DSD128 and DSD256
MacOS: DSD64 and DSD128
--- End code ---
This does imply that it does support at least DoP, since DoP is the only option for DSD on macOS and it doesn't support DSD256 on macOS (but does on Windows, which would require native DSD support along with DoP for macOS). But yeah, other than that, it's kinda odd that it's not working for you, it *should*.

DSD256 uses 705 KHz for DoP. The specs do not say that the DAC supports 705 KHz, although it may. My guess is you need native and therefore ASIO for DSD 256. But trying DoP with Wasapi is worth a try. Wasapi will automatically do DoP. It does not support native DSD. As AD says, using ASIO there should be a check box option to use DoP.
DJLegba:
Looking at your screen shots you are bitstreaming DSD 256 (as you have said) and that doesn't take much CPU power at all (as others have said). I may have missed it somewhere in the thread, but where are the audio files located? If the notebook is pulling the files from somewhere on your network that could easily explain pauses, especially if WiFi is involved somewhere in the connection.
My DAC (exaSound e22) isn't visible to Windows directly. It requires an ASIO driver - and it doesn't do DoP. It sounds like your DAC has the same constraints. If your DAC doesn't show up as an output device in the Windows sound setup it will not work with WASAPI or DoP.

Hi Guys, Thanks for the helpfull suggestions, I set Bitstream DSD in DoP still buffing, tried all the WASAPI settings, still buffing, the files are on my Qnap NAS drive, I had the laptop on mains power, hard wired to ethernet, the drivers are downloaded from the ATC website, they have a setup for the ATC CDA2-CD-DAC Preamp images attached, using these settings the problem files are Flac 192KHz 24 bit and DSD 256, Flac 44KHz and 96KHz 24 bit seem okay, I have contacted ATC but still waiting for a reply
Thanks again for the help
Steve
