"No Audio Output Device is installed"

[Paul H]

I did another restart of my Vista to remove constipation, etc. This time I
have no sound. it says "No Audio Output Device is installed". How do I get
sound back on my Acer 5610 laptop?

Install the drivers. Get them from Acer's website for your specific model
laptop. Install all drivers, including the chipset, as well as any
laptop-specific software such as for power management.

I'll try that. It's very frustrating to have to deal with things
like this - my XP Pro on my old laptop stays like I leave it. But my Vista
Home Premium frequently does me little favors like this. Real time wasters.

After doing a RegCure, Reg Defrag and some MS Updates on my new HP
Laptop I got this same problem. Whatever I tried did not work,
including going to HP for the audio driver, soooo I just went to the
Windows driver error selection and let Windows fix the problem on-line.
It solved everything instantly. Interestingly enough when I was trying
to fix the problem I noticed in Hardware Devices that the audio drive
was not to be found and in other inspections it was alive and working
properly.

DO NOT use registry cleaners! See this
You loaded Vista on a "new Gateway computer"?
What operating system did it come with??

I've read many of the posts already discussing this problem and have not
been able to resolve mine yet! I have a new Gateway computer with speakers
that came with it...Since loading Vista, I get no sound. Te computer
recognizes the driver in the device manager and says it is working. But I
get the No Audio Output device next to the little speaker in the bottom
righth corner of my screen. I've tried updating the driver but I get a Code
10 error: device cannot start; could not load driver software... I've tried
plugging the speakers in other plugs of the tower but have had no luck. I've
updated my system many times. I've spent hours and hours and cannot figure it out.

I installed windows 7 and get the message no output Device is installed. What
do i have to do? Before installed windows 7 i was working with XPHome it
worked perfectly ( the sound ) What do I do now ?

no audio output device installed.
how to I correct this ?

After following all these steps, sound returns, but after rebooting the no
audio output device installed err returns.

Sounds like you need to find sound drivers for your sound card. Is it
on-board sound or a sound card? You need to figure out which and then
what type it is so you can hunt down drivers for Windows 7. Its
possible, since Win7 is still in testing, the drivers you need might not
be available yet.

Ignore all suggestions about reinstalling audio drivers! U suspect that
will get you nowhere. Instead try this:

1. Open your registry editor (regedit from Run prompt). (For your own
safety, either back up the registry, set a restore point or export the
key in the next step.)
2. Drill down to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}
3. Delete any of the following registry entries if they exist under
this key:
LowerFilters
LowerFilters.bak
UpperFilters
UpperFilters.bak
4. Reboot the computer.

I did the automatic Update that it requests on Vista on my laptop and have
the problem with the speaker and red cross with alert saying "no audio output
is installed"
I do not have external speakers so no unplug/plug in issues there.
I have been through all of the online automatic checks and come to a dead end
1) check driver - did online and said it's the most recent version
2) cannot do 'roll back' driver option to older version so thinking driver
up to date
3) checking device is enabled - searched and showed it was 'disabled' so
clicked to enable - this is all on the recording - sound - of control panel.
The 'playback' tab shows no audio device installed and the buttons at bottom
(configure, set default, properties) are blanked out (i.e. cannot click)
At every stage I have restarted and at a dead end.

If anyone can help; I'd be much applied (sorry that I have clicked reply to
this post; I am IT challenged and in need of assistance!)

Sound problems cause by several reasons and every problem may have a
different solution. Once when I had similar sound problem I had found a
suggestion that worked for me. There
are several suggestions given depending on different causes. So I would
like to suggest to check the said website and read all the suggestions
carefully. Maybe they have a suggestion that work for you too...

When I read this thread, I followed the advice yet to no avail. The reason I
had no success was because even though I had downloaded and re-installed the
driver, the driver was not what was missing. The device was missing - the
speakers themselves were gone. So I had to re-install the speaker hardware,
enable it and then once I did that , the driver had something to run from.
After start after re-start, it worked liked a charm but getting to that
realisation was frustrating.
