Problem: No sound from the built-in speaker on Lenovo M57 desktop in Windows 7
This also applies to other brand desktop pcs (Dell, Lenovo, etc)
The sound icon in the taskbar shows a red X on the speaker icon. When double clicking the sound icon, it says detecting problem and then it shows a window:
Which of these devices you want to troubleshoot ? :
* Speakers – High Defenition Audio
The connecter for this device is located on the back side of the computer.
* Headphones – High Definistion Audio Device
The connecter for this device is located on the fron side of the computer.
IT DOES NOT SAY ANYTHING ABOUT THE BUILT IN SPEAKER.
Solving
- Install the latest drivers from the Lenovo support website
- Remove all connected jacks from the audio panels. The connectors can sense if there is a jack insterted, so the internal speaker will be disabled if there is for example, a stereo cable inserted in one of them.
