The dv6000 and dv9000 line are well known for such things to outright product failures. Google if you must but if the factory restore fails to restore sound or ethernet you might try some USB to sound or USB to ethernet solutions since those are really cheap.
DO NOT INVEST IN REPAIR on this model. If you need to know why, just google dv9000 recall and such.
EXAMPLE AUDIO USB and such follows. Be sure to shop around at amazon, frys and geeks.

Hello, I have an HP Pavillion dv9000 and I suspect that the sound card isn't working correctly. I have tried two pair of speakers and neither sound good (the 2nd pair being Bose Companion II, which sound decent on my work computer). I'm wondering if I need to replace my sound card. If so, how much should this cost, including labor?
My computer did get zapped by a power surge during a storm and the Ethernet port does not work (diagnosed w/ an HP tech via phone). I've been using an ethernet to USB adapter and that's been fine. Could the sound card have been zapped too?
Are there any reputable chains to have the work done at? Thank you!
