Installing the software and device drivers
Audio settings
Due to Microsoft Software Regulations the audio device driver USB audio device has been installed onto your PC as your default device for recording and playback. This is also necessary because it allows you to listen to music through your handset with Windows Media Player or make phone calls via the Internet.
For example, if you wish to record or playback sound on your PC (e.g. through your PC's loudspeaker/microphone or connected headphones) while playing a computer game, you must change the settings of the device driver.
ìClick on Start > Settings > Control Panel > Sounds and Audio Devices (Windows XP) or Sounds and Multimedia (Windows 2000), Audio tab.
ìFor sound playback and recording, select the default sound card driver of your PC as the default device instead of the entry USB audio device.
ìClick on OK to accept the setting.
Be sure to set USB audio device as your audio device driver again if you want to use the M34 software.
Using PC loudspeaker/headset with your handset
In most Windows applications you can also give the audio device driver specific settings irrespective of the settings in the Control Panel. This allows you to specify where sound is recorded and played back (PC or handset) for specific applications.
For example, if you have set your PC's default soundcard driver, you can make a phone call with your handset over the Internet while listening to music through your PC's loudspeakers at the same time.
Please note: For Internet telephony with Skype, the device driver USB audio device is automatically set (temporarily) as soon as you telephone with the handset.
