No Audio Output Device

Hi there,
I recently lost the sound on my laptop. When I try to adjust the volume it says there is no audio device installed. I've had this computer since December of 2007 and it has had sound up until today. Please help.
Thank you,
Theresa

Theresa,
You should Uninstall your Audio driver, then re-install it will fix your problem.

  • Goto Device Manager
  • Right Click on your Audio driver component
  • Select Un-Install.
  • Then reboot your system.
  • And re-install driver for audio.

please post your feedback.

My laptop has no audio output device and playback device


Hello....
No Sound, No Volume Control, Mixer not Found, No Sound device installed…etc etc, This is a generic issue with all Windows OS updates....many of the users are facing this issue....this began after an auto update from MS changed many IRQs of Win OS, mainly the Sound and Audio Control system of Windows.
1 - R U facing NO Audio / No Sound issue...?
2 - Is ur Volume Control not responding ?
3 - Is ur Sound and Audio Device in Control Panel Grayed out ?
4 - Do u get a msg "No Active Mixer Devices Installed....when u try to open Volume Ctrl etc etc ?

If ur ans to any one of them is Yes...then u are being spammed by Microsoft....as ur Sound Control IRQ is being frozen by a recent update from Microsoft....

NOTE..THIS…IS…VERY..IMPORTANT...
No file update or any sound driver update can fix it, neither Microsoft is issuing any patch to fix it…or giving any help on this.
Full solution is available in my website (Support page)...it's quite simple process to fix it, and I am not charging any money, just trying to do some service and help everyone affected by this stupidity from Microsoft.

Well, probably they forgot to reinstall audio driver.
Check first that your volume is not at minimum ar audio had been muted, check from 'audio mixer' or from 'control panel/sound, speech.../adjust audio volume'
If volume and mute are ok, download driver from this website and install it again.
You need to select your model, your OS (windows version), and then audio or sound driver download.
Once you download the audio driver (chose save) run the download.
If you do it properly it will work again.
