I have a Toshiba laptop with Realtek sound. I got the same msg that "No Audio device was found" so I simply went into my Control Panel, switched to Classic View, and opened the Device Manager. Then I opened the Sound folder, clicked on the Realtek and told it to DISABLE, then ENABLE. Problem solved.
EDIT: In case this doesn't work, here are two other workarounds:
I also could not find recovery manager, and I also did not have the option when going to device manager and selecting action to scan for hardware changes. However, I fixed the problem by these steps:
1) Go to device manager
2) Select sound, video, and game controllers from the list, and select high definition audio device when it drops down
3)New window opens. Select the driver tab. Click uninstall.
4)Then after it is uninstalled, go back to device manager window.
Select action, and THEN you will have the option of scanning for hardware changes.
Select this option and it will reinstall and the problem should be fixed.
(I have an acer laptop with windows vista but I thought these steps could be useful for others as well)
I also experienced it last night and this is what I did just follow the steps below. I found it thru hp help cntre and it really works out.
follow the steps below:
Click Start and type Recovery Manager in the search field.
Select Recovery Manager .
Click Advanced .
Select Hardware driver re-installation .
Click Next .
Select the appropriate audio driver.
Click Next . The audio driver will re-install.
Click Finish and allow the PC to restart.
Do you have the speaker icon on the lower right? If so, check to see if sound is "muted" (turned off) . If the sound is turned-on it will have two sound waves on the right of the icon. If muted it will have a circle with a slash added to the icon. If muted click on the icon then click the speaker in the new window. Check the sound by changing the volume - it will beep when you change the volume.
If the above did not fix the problem you need to download and reinstall the sound card driver.
Exactly, that is what I mean: these are different problems. Your solution might work if you get "No Audio device was found". However, that is a different message from "no audio output device installed". IN that case, you should reinstall your device drivers, e.g. via 'Scan for Hardware Changes' (refer to previous post).
i see some people have got things to work some didnt. I had hd audio installed on xp but got no audio device..I wish I would have tried disable/enable sound first (just wondering). I reinstalled all sound stuff and even went from onboard to sound card and still had no audio altho all drivers were installed. So here's another solution that worked for me.
>1. From Device Manager (be sure to select View/Show hidden devices), find the 'ISAPNP
>Read Data Port' device from the System Devices list. (Of note: once I successfully
>repaired this problem, this device no longer appears.)
>2. Right click the ISAPNP device, and select "Update Driver"
>3. Select "Install from a list or specific location"
>4. Select "Don't search. I will choose the driver to install."
>5. The step I left out on prior trials: UNSELECT "Show Compatible Hardware"
>6. Be sure that "(Standard System Devices)" is selected under Manufacturer.
>7. Under Model, scroll down until you see "Plug and Play Software Device Enumerator".
>Select this item, and select "Next>".
>8. You will receive some frightening error message that you should probably disregard.
>9. Complete the installation of the driver. You will see your device list magically
>change before your eyes. The other PNP devices will mysteriously become enabled and
>active. If not, restart.
