My windows 7 doesn't read my speakers on my audio sound card or have a speaker sign?but i hear the woofer sound, i go to the sound from open up control panel , i don't have a realtek sound card....
You probably have a conflict with the drivers you installed. Try doing the following:
Go to realtek.com, visit the Downloads section. Pick one of the codec types (not sure if it really matters) and download the driver but DO NOT install it yet.
Right click on My Computer>Properties>Hardware>Device Manager. Find your sound card and right click>delete on every driver you tried, then restart your computer.
Navigate to the directory where you downloaded the codec from realtek.com and install that one, then restart again.
If that doesn't fix your problem, go to your computer manufacturer's website (hp.com, dell.com, etc) and find the drivers for your system to install. Each site is a little bit different, if you tell me which computer you have I can help you download them.
If neither of those alternatives work, then you'll have to do a little more investigating. For starters, where did you find the 6 alternative drivers you installed?
