Up until yesterday, I had sound . I was playing a game and then the sound disappeared. A Red X appeared on the sound control. I shut down my laptop and everything started again.... then the sound stopped and the Red X appeared again. I have shut down more times than enough trying to rectify the problem to no avail.
My laptop is an HP Pavillion dv9810us running Vista as OS.
The sound card is a Conexant HD Smart Audio 211.
I have been searching to resolve this problem and some other issues that started a while back. The initial problems were the webcam and the CD/Rom drive stopped working. I got them back and they worked a few days and disappeared again. I have run MrFixit and nothing. I get the messages that the drivers
I have tried updating the drivers and redownloading... nothing seems to work
In troubleshooting, I was able to find a way to view hidden devices in Computer management. I did so.... and it shows my missing devices... webcam/ cd/rom / sound . When I click on those devices... the icons are grayed out showing they are inactive. I cannot activate them.
Before uninstalling and rebooting my laptop to see if this will reinstall the device drivers.... what am I missing and how can I get all three of these devices to be functional again? I have some online tutorials to do... but can't do them because of the 'no sound' . I am truly aggravated by this.
It appears that this is a common problem that has not been resolved by MS.
Someone please help me out.
