Laptop plays sound through headphones but not through internal speakers

Pavilion DV4
Microsoft Windows 7 (64-bit)

Audio was working fine on my laptop, when suddenly the laptop would not play sound through its internal speakers.  If I plug in headphones the audio is fine.  Running Control Panel/Sound shows "Speakers and Dual Headphones - IDT High Definition Audio CODEC" enabled and set as the default device, as well as "Independent Dual Headphones" (enabled but not default), and "SPDIF (Digital Out via HP Dock)" disabled.  What can be wrong?

Hi,

Please try this first to enable Speakers in Playback devices as follows:

1. Right click speaker icon (right hand corner)
2. Select Playback devices
3. Right click Speakers
4. Enable it and set as Default
5. Click Apply/Ok

Regards.

Cured the problem by uninstalling the CODEC driver, then restarting Windows which then reinstalled it, and now things are ok again.

Thanks for the suggestion - I replied to my own post before seeing yours.  As said in my post, though, reinstalling the driver seems to have fixed things.
