Arcam DAC 23425 User Manual
23425 USB DAC — FAQ
My 23425 DAC is plugged into my PC but I get no audio or I get sound out of my laptop speakers. What gives?
It is possible that the DAC is not the default sound playback device, and thus audio is still coming out of the normal PC sound card or laptop speakers. (e
DAC’s green light shows that the host PC is aware of the DAC as an audio device, and is operating correctly).
To prevent this from happening, please connect your DAC / plug in your rWave before starting your audio application (e.g. iTunes, Windows Media Player etc).
e procedure to change the default sound playback device varies by operating system. As the device is plugged in or unplugged, the operating system may or
may not automatically select the Arcam DAC as the default device.
Windows XP:
Via the Control Panel, open Sounds and Audio Devices.
e third tab, Audio, shows a drop-down box to select the
default sound playback device. Select the Arcam device.
Windows Vista / 7:
Via the Control Panel, select the Sound item. e Playback
tab shows a list of playback devices. Select the Arcam device.
Mac OS X:
Via the Apple in the top-le corner of the screen,
select System Preferences. Under the Hardware
section, select Sound. Select the ‘Output’ tab. From
the list of devices in the Output tab, select the Arcam
device.
Linux distributions:
e two most popular window systems,
GNOME and KDE provide system
conguration utilities to select the playback
device. As this varies by distribution,
by version and by users’ specic
congurations, we cannot provide detailed
instructions here. However, all linux
systems that we tested in 2012 somewhere
facilitated changing the playback device.
Select the Arcam device.
Note: D33 users should select class II
input for Linux. rPAC (class I only) is not
compatible with the current Linux kernel.
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.
Windows XP:
Via the Control Panel, open Sounds and Audio Devices.
e second tab, Sounds, shows a drop-down box to select
the sound scheme. Select the sound scheme called “No
Sounds”. Press the OK button to conrm.
Windows 7:
Via the Control Panel, open Sound. e third tab, Sounds,
shows a drop-down box to select the sound scheme. Select
the sound scheme called “No Sounds”. Press the OK button
to conrm.
MacOS X:
Via the Apple in the top-le corner of the screen, select System
Preferences. Under the Hardware section, select Sound. In the ‘Sound
Eects’ tab, click the tickbox labelled ‘Play user interface sound eects’ to

‘Alert volume’ all the way to the le.
My 23425 DAC is plugged into my PC, has the green USB indicator (not rWave), is selected as the playback device, but
still I get no audio. What gives?
It has been observed during product development and testing that some operating systems occasionally require manual intervention in order for the DAC to install
successfully. is is most likely to occur if the DAC is plugged into a dierent USB port on a PC to where it was previously connected.
Windows XP exhibits this issue. e remedy is to “un-install” the device from the operating system to give Windows XP a clean start when the DAC is next attached.
Follow these instructions (with the rDAC connected) to remove the rDAC from Windows XP, then re-attach the rDAC.
1) Via the Control Panel, select System. In the System Properties, select the
Hardware tab. Click the button Device Manager.
2) In the Device Manager, under the View menu, turn on the option Show
Hidden Devices.
