Windows 7: nforce2 realtek alc650 built-in chip not working

nforce2 realtek alc650 built-in chip not working

I have a Asus A7N8X-X mobo with a nForce2 chipset which brings a
Realtek ALC650 chip for the sound card. The XP drivers work fine until
I restart the system. Then, when I come to the logon screen, the 'logon'
sound plays about half-way through and the system hangs. If I restart
in safe mode and disable the sound card, when I reboot in 'normal' mode
I can login fine and re-enable the sound card to get sound again, but it is
a big PAIN. what am I doing wrong? what drivers are best suited for this

thank you all for your time.

Start here,


and work your way to the download page. You need the Realtek AC'97 driver for Windows 7 for that audio chip.

ok, I've installed the vista version of the driver from Realtek and audio works great until
all of a sudden, without a single warning or sign the sound halts and the computer freezes.
After that, everytime the system starts, when I get to the logon screen, as the logon tune
is playing back the sound 'tilts' and the machine locks again.
I have to re-start in safe mode and disable the sound, then RE-start (!) and re-enable the
What's up with the nForce2 built-in sound chip?!?!? is it incompatible with win7?
Should I get a separate sound card just to be able to have sound in win7?

thanks for your time.

Unfortunately the last bios update for your board was 10/08/04. And they don't even offer a chipset driver update . So to me I'm not surprised to see your having problems with the new realtek AC97 sound drivers.On the Asus site the last update for your sound was 07/07/03 A3.41 for XP So you may want to try a addon sound card. I hope that it will sorte out your sound problem. Fabe
