HP Pavilion dv9000ea sound

Hi,

This is probably due to malfunction driver.

Questions:

1. What operating system installed on notebook. Windows Vista, Windows 7 or other ?
2. Did you installed anything recently ?
3. Do you have driver CD of your HP Pavilion ?

Try following

1. Restart your notebook, if minor malfunction a restart will work.

Thanks, Txsup
