My 23425 DAC is plugged into my PC, the USB indicator is selected and shows green (rDAC only), but I get no
audio. It is the default USB audio device, but I still get no sound (or sound through my laptop speakers) for my open
application.
Some operating systems such as Windows XP cannot switch between dierent audio outputs whilst an application (such as iTunes, Windows Media Player or a web
browser) is running. e solution is to connect and install the DAC before starting any audio applications. If you have already started an audio application before
plugging in the DAC, close and re-open the application.
It is advisable to plug in the DAC before turning your computer on, so that it will be fully initialised before you start any of your applications.
I keep hearing operating system sounds through my hi-fi system when my 23425 DAC is connected. I do not want to
hear sounds every time I get an email, click a link etc. How can I stop these?
Operating system sounds can be turned o using the settings controls for each particular operating system.
