error message sample rate

Getting the message: The Sample rates o the audio input and output devices do not match. Audio cannot be recorded until this is corrected.Use the appropriete operating system or audio device control panel to adjust the sample rates of the input and output devices to use the same settings.  If I change anything, it was by accident. Adobe remote support says it can't help me because it's a CS version. Can anyone help me here? Thanks in advance. Dave
