I also face the same problem finding that my microphone, both external and integrated is not working at all although the audio driver and every settings have been appropriately installed and set.
I also use XP as my windows system and I bought the product in Indonesia.
Can Compaq help me to solve this this problem immediately by sending solver tutorial to my mail : putranda_chemical_ugm@yahoo.com.
I really appreciate if you can provide good service to the customers.
