Question about HP Pavilion dv9720us Notebook
At first please check whether the Microphone on the system works or not.
I mean click on start and in start search type Sound Recorder.
Try to record and play soomething, if it does not play then its an issue with either the Operating System or the Sound Card installed on the Motherboard.
It might be an issue with the driver as well,.
So click on Start and in start search or RUN type devmgmt.msc and then hit enter.
This would take you to the device manager page.
Now locate an option which reads as Sound, Video and Game Controllers.
There would be a + sign next to it.
Click on it, locate the sound driver.
It migh be IDT High definition sound device
or Connexant Driver.
Right click on the driver and then click on Uninstall.
It would ask for a confirmation.Click on Ok to confirm and then look right at the top of the screen and locate an option which as ACTION.
Click on it and then click on SCAN for Hardware Changes.
Restart the computer and then again try to check whether the sound recorder works or not.
If the sound recorder works then its an issue with the Application which you are trying to use over the web and if its not then its an issue with the sound card.
For that you need to check in the BIOS.
Restart the computer and tap on the F10 key, it would take us to the BIOS set up...now try tapping any keys...
If the keys make a beep sound then the Sound Card is fine then you need to reinstall the Operating System.
And if the keys does not beep, Call Hp they would take the notebook in for repairs...
