It's not a huge problem, but just found out the WIN 7 audio driver
for my HP notebook Pavilion dv2312us will not be available for another 2-3 months. Using the current driver, I get a POP sound when it goes into sleep mode or shuts down. I also don't have a mute function. I hope the POP sound is not damaging to the computer.
I was on the driver page for this computer and the Win 7 audio driver is not listed. So then I went into a chat - he gave me a driver that wasn't compatible at all. Had to go back to my other generic IDT driver which causes problems above. FWIW.
