Dropouts Happen In High Bit-Depth Or High Sample Rate Audio; Patching An Effect Into Sonar Causes A Dropout - CAKEWALK SONAR User Manual

To mute your sound card's direct sound:
1. Open the software mixer that controls your sound card. If your sound card uses the Windows
mixer, open the mixer by using the Start > Programs > Accessories > Entertainment > Volume
Control command, or by double-clicking the speaker icon on the Windows taskbar.
2. In the Play Control window of the mixer, check the Mute check box in the Line-In column, or in the
column of whatever jack your instrument is plugged into, and close the mixer window.
Dropouts Happen in High Bit-depth or High Sample
Rate Audio
If you are hearing consistent dropouts/clicks in your audio and if your project contains high bit depth
(32/64 bit) or high sample rate audio (88.2K or higher), it may be indicative of a too small I/O buffer
size. If so try a higher I/O buffer size like 256 or 512. If audio problems persist, reset to 128 and try a
different remedy.
Use the Options > Audio command to open the Audio Options dialog, click the Advanced tab,
and in the I/O Buffer Size (KB) field, enter 256 or 512.

Patching an Effect into SONAR Causes a Dropout

You may have simply reached the maximum number of tracks and effects your CPU can handle.
However, if your CPU meter doesn't appear to be maxed out, or other plug-ins seem to work, you
may need to address the problem by editing a line in the Aud.ini file.
Using Notepad, open the Aud.ini located in the directory where you installed SONAR. The default
value of the ExtraPluginBufs variable is 0. Try changing that value to 1, saving Aud.ini and
patching in the effect that caused the dropout. If it still causes a dropout, try changing the value in
ExtraPluginBufs to 2. Continue to double the value in this variable until you reach 128 (4, 8, 16,
32). If a value of 128 does not fix the problem, it is time to try something else. See Dropouts and
Other Audio Problems in the online help for more information about potential reasons for dropouts.
