Crackle M4800 Audio when the sound is played (if no sound has been played for a while)

I have a new DELL Precision M4800 running Windows 7.

There is a distinct noise pop crackle that occurs when the sound is played (if no sound has been played for a while.)

If the laptop is audio playback currently it looks good, but if the laptop is quiet for a while and then something like an e-mail notification is available, crack/pop noise happens as the driver/speaker is trying to wake up.

The problem occurs with the laptop connected and detached.

-Edit

The solution for me was provided by pknb below.

Reference Dell Open Audio in the control panel. Go to advanced, energy management. Disable the option to disable audio devices.

I do not have the Audio from Dell driver installed - and it seems that maybe the default setting is that the speakers put in 'sleep' in the context of a power saving mode. Looking at my description above I even referenced at the time of the issue seemed to be that the speaker was not long in 'waking '. In any case after you change this setting the problem now seems to be resolved.
