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 dierent 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.
