check Device Manager to see if it is listed with a red or yellow icon beside it. This would mean it is detected but requires drivers.
Drivers can be found at HP web site

If it is not detected it could be a hardware problem, in which case I would try the driver software to see what it says about the device.

Nothing in the device manager for Audio or Sound devices. I'm suspecting hardware.

Could be a reflow of solder joints may fix it.
