USB – PWD not recognized, or no sound via USB
To play music from your computer into the PWD via USB you must have a driver installed that
communicates with the PWD. On a Mac computer with OSX or Snow Leopard 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 USB driver. You can also
go to Applications->Utilities->Audio Midi and select the driver as well as set the same rate.
On Windows the drivers are not yet available for automatic recognition. You will need to download the
PS Audio USB driver which can be downloaded here: http://updates.psaudio.com/MarkIIUSBDriver/PS
Audio – USB Audio 2.0 Driver V1.22.0.zip
You can also contact our support staff via email or phone or simply go to www.psaudio.com and click
on the support page for the download. You must then unzip the driver and install it on your Windows
machine. Once installed, Windows will recognize the PWD 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. In any of
these cases the remedy is quite simple. Remove the device and force Windows to reinstall the driver and
the device.
Right click on MY COMPUTER and select PROPERTIES. This will populate a window titled “System
Properties”. From “System Properties” select “Hardware” -> “Device Manager”. Once in “Device Manager”
look for “Sound, Video and game controllers”. If the PWD is correctly installed you will see a Device label
“PS Audio USB AudioLink” if you do not see this, you will see a warning symbol next to a device with an
incorrect or missing Driver. Right click on the symbol and select “Uninstall”.
