Hi
i have to change de hard disk, and install the windows 7 home premium 64 bits, the process works fine, but when i install the audio driver the sound works until y shutdown the notebook, when i restart the pc appears a message saying "no audio device is found", if i click in solve problem (i dont sure this is the correct name in english), windows "reinstall" the driver and the sound work until i restart the pc.
the driver is realtek high definition audio controller, i download directly from the manufacturer's website, and i tried with the driver came in the Dell's cd.
when i uninstall the realtek, windows install the windows high definition audio, he works but dont difference between speakers and headphones and both sound at the same time. this driver present the same problem when i restart the pc appears a message with no audio device is found.
in the device manager the realtek audio has a error code 39, the same for windows audio driver.
and i see once the intel r high definition audio has a error code 10.
i tried some solution in the windows forum like use fix-it and delete some rvalues from regedit, no one works permanently
someone knows how to fix the problem?
i hope you forgive me for some english mistakes, its not my native lenguage
