New features in SONAR 8.5

Minimize driver state changes

SONAR 8 has a new option to no longer reset audio devices each time playback or recording starts.

This option minimizes device state transitions in response to transport operations. When enabled,

SONAR attempts to keep the device in a running state as far as possible.

To configure the MinimizeDriverStateChanges option

1. On SONAR’s Options menu, select Audio and then click the Advanced tab.

2. Under Configuration Settings, click Edit Config File.

The Aud.ini file opens in the default Windows text editor.

3. In Aud.ini, locate the entry called MinimizeDriverStateChanges and set it to the desired

value. For example:

MinimizeDriverStateChanges=1

Valid values are as follows:

• 0 = off.

• 1 = On for ASIO only (default).

• 2 = On for WDM only.

• 3 = On for both ASIO and WDM.

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.

Note: The MinimizeDriverStateChanges variable only applies when using ASIO or

WDM driver modes, not when using the MME driver mode.
