Hi there
Try opening up
Options>Audio, click on the
General tab, and make sure your soundcard is listed in the
Record Timing Master field. If it's not, click on the drop-down arrow and see if it's listed. If so, select it and click
OK.
Failing that, you could try running the
Wave Profiler (on the same
General tab).
What soundcard are you using, and what driver mode are you using?
