Windows Sounds Interfere

By default, Windows assumes you want to be notified with a sound (typically a chime) whenever various program events take place, such as when a message pops up or new mail arrives. Although this is almost always inappropriate when Daqarta is running, Daqarta cannot suppress these sounds automatically.

To turn them off, you must go to Start - Control Panel - Sounds and Audio Devices and click on the Sounds tab. In the dialog that appears, go to Sound Scheme and use the scroll button on the right to select No Sounds.

Under Vista or Windows 7, 8, or 10 you can right-click the little speaker icon in the system tray and select Volume Mixer, then mute the Windows Sounds by clicking the little speaker icon below the slider. You should probably mute any other applications as well... or better yet, close them completely. See below.

Note that Daqarta automatically blocks the annoying beep that Windows inserts when the Master output slider is changed via the Windows Mixer. (Daqarta's own controls never invoke the beep.)

In addition to Windows sounds, some systems (at least XP and later) can secretly reserve part of the sound card range for other sound applications, allowing them to interfere. Make sure all other sound applications are completely closed when Daqarta is running.
