Greetings.
Let me to share the frustration and more importantly, a possible fix with all of
you who have got the same plaque.
Before I go on, let me to tell more about the configuration of this issue found...
it is not laptop / notebook but it is a HP desktop using an Asus motherboard, comes
the same Realtek HD Audio chip like many other motherboards out there.
I have got the original, updated drivers from HP, Asus and Realtek. But uninstall,
reinstall, update, rollback, manually pick the driver location would not help. For
references, this is the most current driver from Realtek...
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false#High%20Definition%20Audio%20Codecs
I Google many places and finally stumble to a site NeoSmart Files...
http://neosmart.net/blog/2006/vistas-hideous-wakeup-support/
It points out the root cause is about the ACPI / Power Management in the current
build of 32-bit Vista. Then it led me to the Micro$oft documents confirming with
the issue...

If you have put your computer into Sleep/Deep Sleep/Hibernation mode before, AND
then Shut Down/Restart it, the issue we are sharing may likely be the same cause.
It reminds me about the early days when I beta test with the 32-bit beta / RTM builds
did not show any problem. The 64-bit Vista also runs fine with same routine.
So I thought to myself, download and run the fix would be done... NO! The update
patch told me "it does not apply to my system". ???!!!! Back to square one.
I track back my procedure again and again. Then I discover a possible explanation
of how the fix should really be. Simply put...
- Uninstall the Realtek driver - whether it is from the OEM or Realtek - in Programs
& Features.
- After that, restart BUT go into the SAFE mode by keep tapping the F8 during the
POST screen. Choose Safe mode (without the network or command prompt, just safe mode)
- When loaded into the Safe mode, go to Device Manager, look up the Sound device
installed. Uninstall the Realtek HD Audio Device.
- Then redetect the driver by refreshing the Device Manager to look for any hardware
changes. It should install the generic Microsoft HD Audio Device driver instead of
the Realtek ones.
- I prefer the manual intervention but Vista seems has to do it by itself. So when
it comes back AND it shows Realtek other the generic one, change it manually in the
list.
- Restart the computer. The sound should come back during the splash screen at least
in my case.
- If you have got Areo theme active before, it will switch to classic theme because
of loading into the safe mode earlier. Just change it back to Aero theme in Personalise
> Theme settings.
- Now, to prevent future recurrence, I set the active Power Plan in Power Options,
NOT to go to Sleep/Hibernate at all! You need to go into Advanced settings to check
all items by clicking all the drop boxes. Also, I have changed the "power button"
in the Start Menu from "Sleep" to "Shut off".
So try this and update us with your findings/observations/ solutions. Good luck.
