I'm using an HP desktop with windows XP. I recently restored my computer, wiped the hard drive and all, and have been having problems with my sound. My sound card is Realtek HDMI audio (or something like that).
Initially, the problem was just that there was no sound at all. The first thing i tried was downloading a new driver manually, from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false. After doing so, and restarting my computer, my computer was suddenly unable to recognize the sound card (when i run => dxdiag, it says no sound card was found; whereas it had recognized the card before i downloaded this driver).
After talking to a friend, i learned that i could update drivers automatically by using the device manager. So i did that, thinking it would replace what i assumed was a bad driver i had downloaded. Instead, it just told me that it can't find a better driver than the one i have.
So then i figured that the driver had been corrupted during installation or something, so i went to add/remove programs and removed it. After doing so, i went back to device manager and it no longer had my sound card under "Sound, video and game controllers". However, there is now a "PCI Device" under "System Devices" with a yellow ! next to it. When i attempt to install it, it asks me for an installation media (which i don't have) and is unable to install it without that.
So i went back to the Realtek download page and tried downloading/installing "ATI HDMI Audio Device", thinking maybe that is a substitute for the disk that i need. When i attempt to install this, i get "No driver was supported in this driver package." I then reinstalled the original driver i downloaded, and (after restarting) tried installing the last one again, with the same results.
I am so befuddled at this point and don't want to make the problem any worse than i already have. Help?
