I get an error message when I change a project to
24-bit audio
Some audio devices, especially USB devices that use WDM drivers, can not operate in 24-bit mode
unless a variable in SONAR’s Aud.ini file is set to 1. The variable is Use24BitExtensible=<0 or 1>,
which goes in the [name of your audio device (‘n’ in, ‘n’ out)] section.
To access the Aud.ini file from within SONAR, go to Edit > Preferences > Audio - Configuration
File and click Edit Config File. After you update and save the Aud.ini file, click Reload Config
Settings.
For more information, see “AUD.INI” on page 1301.

Bouncing tracks takes a long time
By default, SONAR uses a buffer for bouncing tracks that is the same size as the (Mixing Latency)
Buffer Size value that you set in Edit > Preferences > Audio - Driver Settings. But with some
projects, especially ones that use certain soft synths, the bounce buffer needs to have its own value.
To change the BounceBufSizeMsec value
1. Go to Edit > Preferences > Audio - Configuration File.
2. In the Properties list, change the BounceBufSizeMsec value to 100, or a value between 0 and
350 so that the bounce buffer will use a more efficient size for bouncing, which has different
requirements from normal playback latency.
For more information, see “AUD.INI” on page 1301.
More “Frequently asked questions” on page 1251.
Note: At a value of 0, the bounce buffer is the same size as the (Mixing Latency) Buffer Size
value that you set in Edit > Preferences > Audio - Driver Settings.
