 Another program may be using the sound card at the same time. (May happen with
older versions of Windows.)
 Update or install your sound card's drivers. Check the manufacturer’s website for
the latest drivers and documentation.
SOUND IS BREAKING UP, POPPING, OR CLICKING
When playing back a project, if the audio sounds like it is starting and stopping
quickly, it could be because the computer is over tasked due to other programs running
at the same time. Your computer may not be powerful enough to mix the audio in your
project. Here are some things to try.
Always shut down as many unnecessary programs as possible. It may even be
advantageous to temporarily shut down virus software. (We don’t recommend doing
this unless you’ve done a full scan and are not connected to the Internet.)
Increase the audio device latency setting. (Go to the Preferences>Sound Device in the
Main Window menus.)
Freeze a track if there are many effects or compressed audio formats on the track.
(Frozen tracks use far less CPU resources.)
Turn off some display features. Go to the Preferences>Display and try limiting the frame
rate or not drawing audio and MIDI data. Turning off logging may also help.
Make sure that you have the latest drivers for your sound card. Visit your sound card
manufacturer's website to check for updates.
Note the CPU meter in the lower right corner of Mixcraft; this indicates how much
CPU Mixcraft is using compared to the entire computer's entire CPU usage.
