All music players migrate from Direct Sound interface to the WASAPI as a default output Device. Latest builds of Windows 10 has a new programming interface for the apps store, it is a simplified access through the WASAPI. For legacy applications there are two steps:How would you activate it? Like say with jRiver?
1. Enable WASAPI exclusive mode in Windows Sound control panel for your device. It is neccessary for allowing applications to bypass Windows system mixer limitation and sound degradation, as Windows do a poor job. And it has a negative effect on USB transfers control. If it is not done, then USB transfer mode depends on the first application that opened a pipe to the device. It is not what you want.
Enable two options in the advanced section:
- allow application to use exclusive access
- give application a priority
2. Now all things depend on the music player. In Foobar install WASAPI plugin and select "WASAPI Event (your driver name)" output device. I don't use JRiver, but these links should be sufficient:
On the second link do not enable a second option. If default is not working, then your device is older and do not support transfer speed synchronisation with a DAC clock.
