Description of Issue

New install. Almost everything working well- sounds GREAT!!
Under the audio page the mytek dac is listed twice.
WASAPI works fine.
It is also listed as Mytek Stereo Dac ASIO. When I hit the enable button I get a device intialization failed error message. I would prefer to try to use asio. Asio on this dac works fine on jriver, same machine.
Mytek driver is up to date.
Please let me know how to proceed.
Thanks

Not official support, but, I would first as a test, Disable the Wasapi device. Reboot the device and the Roon Core and see if you get the initialization failed message.

Mytek Stereo192-DSD-DAC ASIO Driver Device Fail

After experiencing the problem and sending this post I was able to enable the Mytek ASIO driver. The main thing I did was disable all of the other sound drivers except the Mytek driver. I then disabled the Mytek WDM driver. When I tried the Mytek ASIO again it enabled. I tried to get it back in a bad state and I couldn’t. Its been working fine since.

That worked!!
I tried the asio driver first and it failed, not sure why doing it again worked- but it did!!
I will not argue with success!!
Thanks
sounds great so far

My back of the envelop guess is that ASIO requires exclusive access to the DAC by default. If it cannot get exclusive access it usually means that something else is already engaging the DAC.
