4. Save Aud.ini and close the Windows text editor.

5. Click Reload Config Settings to reload the current audio configuration settings from Aud.ini.

Queue buffers

SONAR allows you to set the number of queue buffers in Edit > Preferences > Audio - Driver

Settings. A higher number of queue buffers will take longer to fill, and therefore cause an increase

in latency. A lower number of queue buffers decreases latency, but may cause “dropouts.” The

default setting is 2. For more information, see “Mixing latency” on page 1117, and “Dropouts and

other audio problems” on page 1123.CPU meter/Disk meter/Dropout indicator

SONAR has several tools to help you identify and correct audio problems, including the CPU meter

and Disk meter in the Control Bar’s Performance module, and the Dropout indicator in the Transport

module.

Figure 313. The Transport module.

The Dropout Indicator appears whenever your project requires more resources than your CPU,

main memory, and disk can supply. For details, see “Dropouts and other audio problems” on page

1123.

Note: The MinimizeDriverStateChanges variable only applies when using ASIO or WDM

driver modes, not when using the MME driver mode.
