Sapphire HD 3850 256MB GDDR3 188-01E63-00ASA 产品宣传页

Please read this notice in its entirety if you intend to install your new Sapphire HD2400 or HD2600 
series graphics adapter into a computer running Windows XP as the operating system.  This notice 
is not applicable if you intend installing it in a computer running Windows Vista.

Part of the feature set of your new Sapphire graphics board is that it has an HD Audio Controller built 
into the board to allow you to easily and seamlessly output both video and audio via an HDMI output 
using the Active DVI-HDMI converter may have been included in the box.

For this reason, part of the driver installation routine also installs the appropriate driver for the HD 
Audio Controller.  The behaviour of the installation of this driver means that it automatically sets the 
default audio device to be the HD Audio Controller on the graphics board.  Consequently, audio will 
no longer be routed to the normal speaker output via your previous add in sound card leading you to 
believe that your audio has somehow been ‘broken’ by the driver installation.

This is not the case.  If you intend to use the HDMI output as your primary output and want the audio 
routed along the HDMI cable then you do not need to do anything further.  Once you connect your 
HDMI display you will find the audio is also present.  If you do not intend to use HDMI or only want the 
video to be routed via HDMI and the audio to be routed via your existing sound card output then you 
need to change the default audio device from the Windows XP Control Panel.

Please find below a description of what you will need to do to achieve this.

The top section of the window refers to 
‘Sound Playback’  This is what needs to 
be changed.  Click in the pull down box 
for the ‘Default device’ and change it 
from ‘ATI HD Audio rear output’ (which is 
the HDMI output via the graphics card) 
to your normal sound card.  There is 
usually only one other to choose from.  
Finally click on ‘OK’

Any application that outputs audio will 
now need to be restarted but you will 
find that the audio is now routed from 
your sound card.

Should you wish to output audio via 
HDMI in the future, please carry out the 
previous procedure but choose ‘ATI HD 
Audio rear output’ as your default audio 
device.
