After installing a Nvidia GeForce 8400GS video card the sound on my Pavilion a1540n desktop loses sound every 2-3 days or as soon as I hibernate the system. The only way I can get it back is to disable then re-enable the Realtek audio device and then turn the computer off and back on. It will not reappear with a restart it has to be a cold boot. I updated the software and drivers on the video card and checked for updated drivers from HP on the sound but nothing helps. A friend mentioned that on-board sound can be more sensitive than a separate sound card and something is probably in conflict. Any suggestions before I have to put out extra bucks for a new sound card? I really don't want to do that! Your help will be much appreciated and Merry Christmas to all!
RG, I am not certain that I agree with your friend. Normally, the onboard sound will be less of a problem than a separate sound card. I would update the driver for the onboard sound and also the latest driver for the video card. Let us know if this helps.
