Topic: WASAPI why only 44.1

Good day.
Support ADI2 DAC / PRO when installing in JRiver/ROON-WASAPI driver it is possible to play only the frequency 44.1 since other frequencies are not reproduced and not supported.
Actually why the device does not support WASAPI driver on WIN10?

Re: WASAPI why only 44.1

Please let us start with correct statements. The driver does support Wasapi in Windows 10. But the driver lacks the capability to let applications change the sample rate, so you have to manually do this in the driver's Settings dialog. This is caused by the driver being capable of multi-channel, multi-client WDM/ASIO operation as well as multi-interface usage. The driver was not designed and built to support just two channels of playback.

And this will not change. Please use ASIO for automatic sample rate changes.

ASIO also has the advantage to support sample rates above 384 kHz, not screwing up Windows' Audio Enhancements above 192 kHz sample rate, and not needing workarounds to support higher DSD rates by packing more data into half the sample rate (768 kHz = DSD256).

Found this thread while trying to figure out how to make my sample rate on the ADI2 while using Windows match the sample rate of the source material ... how do I "use ASIO for automatic sample rate changes?"

Thanks very much

Re: WASAPI why only 44.1

By using a software that supports ASIO. Otherwise, as you have the DAC, the topics Class Compliant and automatic sample rate change have been discussed and explained in great detail:

The current manual online also had been updated with these infos:
