How do you restore a deleted sound function on an Acer 5735?

Answer 1

The first place to look is the Device Manager. If there are any driver issues they will be highlighted here. If the drivers are damaged or cannot be found, re-install the audio driver from the installation discs or download the latest driver from Acer support.

If the drivers cannot locate the hardware itself, it's possible the hardware has been disabled in the BIOS settings. Enter the BIOS setup program at boot-up and examine the settings. Do not change anything you are not sure about, but take note of all settings (as a backup) and look them up on the internet later. However, if any setting indicates the audio-hardware is disabled, re-enable it and save your settings. Once the system is rebooted, try installing the drivers again (they should install automatically once the hardware is detected).

Assuming the driver is installed correctly, you should have audio functionality. You can test this by running mmsys.cpl (or open the Sound control panel applet). Look at the Playback tab and ensure the correct default output is selected, click Configure, then Test. If there is no sound, run SndVol.exe to ensure the volume is not muted and that the correct output device is selected. If the built-in speakers have a separate volume control (often found on the keyboard function keys) adjust these accordingly.

If there is still no audio functionality, there may be a hardware issue (a faulty component). Laptop sound cards are often integrated into the motherboard which can be expensive to replace. However it may be that a cable has simply worked loose. Consult your warranty or seek professional advice for replacement parts or repair.
