"No audio output device is installed" upon wake-up...

I recently purchased an Acer model E-380 computer with Vista installed on it.
I am using the basic two front speaker setup made by Acer. Randomly upon
waking up from a sleep condition, I will get the red X on the speaker icon
saying "No audio output device is installed". In the device manager the
RealTek device is gone. Then when I restart or put back to sleep and turn on,
the driver will be back. Is this a known issue, is there a fix?
The Realtek High Definition audio driver for Vista is
installed(sometimes...lol).
Thanks!

Woah! Someone else has the same problem as I! I have a 965P-DS3
(Revision 2) Gigabyte motherboard that does the same thing. It has
the Realtek ALC888 HD audio codec chip. Does your motherboard by
chance use the same chip?

I posted here before and someone said it was a BIOS problem. Later, I
contacted Gigabyte. After many messages and tests they said Vista is
buggy and to wait for Microsoft to fix it. Now that I see you have
another brand of motherboard with the same problem. Maybe this is a
Vista problem and not a motherboard problem. BTW I have no problem
when using XP.

BTW, working with Gigabyte, I think I ruled out the driver causing
this. Using the driver that shipped with Vista or the new one from
Realtek made no difference. I even uninstalled the sounddriver (via
the device manager) and put the computer to sleep. Upon waking up the
computer, sometimes Vista detects the audio device and reinstalls the
driver. Sometimes it doesn't. The problem appears to be that the
Realtek audio codec sometimes is not being initilized or detected when
the computer resumes from a "suspend to RAM" sleep state.

Has anyone else had this problem?

I just found this problem in the MS support knowledge base. It's
article KB929685. Here's the link:

http://support.microsoft.com/kb/929685

Unfortunately, when I tried to instale the patch I got the message:
"The update does not apply to your system".

Yeah I got the same message! wonder what system this is for then! I am
emailing MS and asking them...cause this sounds like the fix for the exact
problem seen.

Please keep me updated on what Microsoft says. I passed this
information on to Gigabyte and ask them to check with Microsoft.

Justin I hope you are still follwing this thread. Someone else with
this problem has posted a message here:

http://groups.google.com/group/micro...6d6389b78167d4

He has an ASUS board and a SoundMax AC' 97 codec (not HD audio like
us). Please read my last post in the thread and post your system
specs in the thread like I did. Maybe we have something in common
causing the problem.

Folks,

I'm using Vista Ultimate x64 and I had exactly the same problems with my
realtek onboard audio (ALC882M).

Previously, I'd had a Soundblaster XFi but decided to get rid of it. I
assumed the problems I was having were because some Creative drivers were
still in my system and causing conflict.

When I removed the XFi and activated the onbaord sound, it was only detected
by Vista as an 'Unknown PCI device' ie it made no mention it was a sound
device.

I tried the latest drivers from my motherboard (MSI 975X Power Up! Edition)
website AND the drivers from the Realtek site - neither worked.

I was about to re-install my XFi when Windows Update told me there was an
important update I should download, something about HD audio devices not
resuming properly and causing windows to crash. So, I installed it and
restarted the computer.

Lo and behold, on start up, the 'Found new hardware' notification came up,
and Windows then proceeded to install the drivers which had thus far failed
to install. 2 minutes later and BINGO, one fully working Realtek audio device
with 7.1 surround sound.

Hope this helps anyone with the same issue - read more here:
