I have a Dell Inspiron D531s, it’s just over a year old. 2 months ago I started getting “No audio output device is installed” only after it comes back to life after sleep. After I restart it I get sound, sometimes after 2 restarts. I uninstalled the sound driver. Purchased a sound Blaster CD from Dell, downloaded a new driver from the net, Changed the BIOS, then changed it back. Was going to buy a new sound card, but no one can seem to figure out which card, finally some said $150.00. I’m frustrated.

Re: Another "No Audio output device is installed"
Actually the problem that you have is the power management. Go into Control panel then the power settings. Make sure to turn off system standby. The reason that it is not installed after it comes from sleep is that it is not reenabling. THe computer turns off the component during sleep.

The audio output device in your computer is the audio adapter board (or circuit). This is the device that produces sounds and send them to the speakers.
If you get a message telling you that there is no Audio Output Device detected, or that the Audio Device is not working, that usually means that there is a problem with the audio driver.
In that case the problem is often fixed downloading and reinstalling the drivers for your audio device. If there is a problem with the audio output device, go to the computer manufacturer website (e.g. Dell, HP, Sony etc.) and download the audio drivers for your specific model. When download is complete install the drivers and restart the computer.
Assuming you're running Windows Xp you should try uninstalling and then reinstalling this driver from dell: http://support.dell.com/support/downloads/format.aspx?c=us&cs=19&l=en&s=dhs&deviceid=6466&libid=3&releaseid=R99254&vercnt=2&formatcnt=0&SystemID=INSPIRON%201200&servicetag=&os=WW1&osl=en&catid=-1&dateid=-1&typeid=-1&formatid=-1&impid=-1&checkFormat=true
Always check in the device manager after installing a driver to see if any problem accured.
First installations of Vista some times fail to detect the hardware on older systems, like my Dell Inspiron 9100 laptop. However, after running Windows Update several times automatically detects the missing drivers and installs them automatically.
Try that, if that is your case. Other than that, try uninstalling the device using Device Manager, and immediately reboot the system. Vista will detect the missing hardware and will reinstall it from its list of known drivers. As your last resort, try going to your system's manufacturer's web site and go to the Support page. Most manufacturers have a Drivers Download page.
What type of computer is this?
If you are building this unit yourself, and your motherboard does not come with audio. Then you must purchase a Sound card. I think Soundblaster is a good choice...Try clicking on sys information and see if you system has Audio. if so then check and make sure you have plugged your speakers in too the right output port, look at the back of the computer its usually the green jack.
go to start - control panel - system and maintenance - system - device manager, locate your sound card and uninstall your sound drivers, rebbot the computer and vista should reinstall them for you and they should work again
try the following steps.
1. Right click My Computer Icon and select properties then select Hardware tab.
2. After selecting hardware tab click Device Manager button.
3. After clicking it list down all devices that you have and expand the "Sound Video and Game Controller" by click the clicking the plus(+) sign and it shown you the list sound devices.
4. In the list, look for explanation point(!) in yellow color beside device name (this means that device driver is missing or not properly installed)
5. Select the device name and press right click and choose uninstall.
6. After uninstallation click Action Menu and select "Scan for Hardware Changes" (this will scan the other device which is not yet installed in the system)
7. System will prompt you to load the Audio driver(insert the Audio device cd driver) if your using a built-in audio use your desktop/laptop device driver cd and locate the driver folder from cd and choose sound or audio folder the list and select the proper windows for your computer.
8. after running installation the volume bar should appear in the right side of your desktop allong with computer date & time. if not restart your computer.
