In order to have the sound correctly routed to the ALVA BC640 in Windows XP,
please select the audio playback devices for the default audio device, the Bluetooth®
mono playback device and the Bluetooth® stereo playback device. Please note that
these options are not available in Windows Vista.
The name of the default audio device depends on the brand and model of the sound
card manufacturer. The mono Bluetooth® device is in most situations labelled as
Bluetooth-audio. To select the stereo Bluetooth® audio device first, you will need to
create a Bluetooth® stereo connection:
1. Open “My Bluetooth Locations”;
2. Go to “Find Bluetooth Device”;
3. Search for ALVA BC640 FP and make sure it is paired;
4. Press Enter on ALVA BC640 FP to create the stereo connection;
5. (Re)start the ALVA BC6 Bluetooth® settings application;
6. Select high quality Bluetooth® audio to set the stereo Bluetooth playback to
audio device.
To save the settings to all users, make sure the “Save to default user” is checked and
press Enter on the “OK” button. To save the settings to the current user, make sure
the checkbox is not selected.
