I've just bought a new hp pavillion dv9010 and I had good sound for the first week then one morning The sound was non-excisting. I've tried all the basics with volume and mutes and drivers. I restored the computer to an ealier time when I knew I had sound and still nothing. I updated everything I can from windows to everything that applies to me on the hp website. I've went into the bios and checked that all out and all is good there. I'm not getting any error's but I have no windows sounds no music or movie or anything for sound. I've called hp and spent an hour and a half with them to no avail. I've googled this problem and tried all sorts of senerios and nothing is helping. I know the soundcard still works because I get the little beeping sound when I press my volume control on the base of the laptop. It just seems that something is not letting sound out?? I have rolled back drivers and got the newest drivers and now windows says I have the best possible driver avalible. If there is anybody that is familliar with this problem can you please give me some feed back on the problem!! Thank-you By the way my sound chipset or card is a Conexant High Defintion Audio and my operating system is Windows XP Media Edition
