No audio output device installed - Acer Aspire 4520-5582 Notebook

Well it is possible that the audio driver installed is not the one compatible with you computer board. Try downloading the specific driver needed for your computer's official website. This should solve your problem.

Hi.

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.

You have to install the audio driver for the audio device first. As for the output audio it is for speakers connect/plug into to the output audio port.

For no Audio output device installed message, go to device manager uninstall the audio driver. Reinstall the audio driver from either Windows update or from the manufacturer's(your Computer or Laptop) Web site.

why realtek ac97 audio not being installed in a windows vista?

Hi,

This happens because the video card has hdmi output. Since hdmi output can carry audio signals also, the audio driver gets disabled. Uninstall audio driver and video driver both, install the video driver, and then install audio driver. after installing the audio driver, in playback and recording devices choose choose the audio output device you purchased along with the computer. This should fix the issue.

Revert back for any clarifications.
