Enabling and Disabling Audio Devices
Your computer may have several installed devices like FAX modems and
software synthesizers that Windows recognizes as sound cards containing
audio drivers. You do not want to use these devices for audio input or
output. If they are listed as audio drivers in the Audio Options dialog box,
you need to disable them.
To Enable or Disable an Audio Device
1. Choose Options-Audio to open the Audio Options dialog box and click
the Drivers tab.
2. In the Input Drivers and Output Drivers fields, do one or both of the
following:
• To enable an audio device, click the name of the device so that it is
highlighted.
• To disable an audio device, click the name of the device so that it is
not highlighted.
3. Click OK.
Disabling a device in the Audio Options dialog box usually prevents
conflicts with other audio devices. Occasionally you may need to disable a
device in the Windows Control Panel.
SONAR also allows you to choose the sound card whose clock should be
used to control recording and playback timing (if you only have one sound
card, SONAR automatically uses it). Every sound card’s clock crystal is
slightly different, which causes minor differences in the actual playback rate
on each card. These differences may lead to slight synchronization
problems if you use one card for recording and a different one for playback.
Generally, you should choose your highest quality sound card for both
recording and playback timing. Note that while some multichannel sound
cards have multiple drivers, most sound cards have only a single audio
driver.
To Select Playback and Record Timing Masters
1. Choose Options-Audio to open the Audio Options dialog box and click
the General tab.
2. In the Playback Timing Master and Record Timing Master fields, select
which sound cards you want to control playback and record timing,
respectively.
3. Click OK.
