Owner’s Reference DirectStream DAC

USB – DirectStream not recognized, or no sound via USB

To play music from your computer into the DirectStream via USB you must have a driver

installed that communicates with the DirectStream. On a Mac computer with OSX Yosemite

or later the drivers are already available and the unit should be automatically recognized. You

can then go and choose the PS Audio USB driver to play to by going to System Preferences-

>Sound and select the PS Audio PerfectWave DSD. You can also go to Applications->Utilities-

>Audio Midi and select the driver as well as set the sample rate.

WIndows 10 compuiters come with the driver installed as well. You siumply need to seklect the

DSD DAC from the sound window as the playback device.

Windows 7 operating systems and older do not come with appropriate USB audio driver

software installed. You will need to download the PS Audio USB driver from the PS Audio

website.

You can also contact our support sta via email or phone or simply go to

www.psaudio.com and click on the Downloads page for the download. You must then

unzip the driver and install it on your Windows machine. Once installed, Windows will

recognize the DirectStream and allow you to select it for playback from any program on

your computer.

If you are unable to obtain sound via USB on a Windows based device it is most likely the result

of a partial or incorrect driver installation.

You may have also experienced a pop-up window asking you to provide the correct driver.
