I have no sound and i can not see the volume control

Dust accumulation on the inside of the volume control. With the amp off rapidly change the control from stop to stop several times or until the sound is no longer choppy. If this doesn't work then the volume control will need to be replaced. This trick works for a car radio too.

Volume on an Acer Laptop
Acer laptops are typically sold with pre-installed Windows operating systems that offer sound-adjustment features for increasing the volume on the laptop's built-in stereo speakers.
These same functions can also be used in tandem with external speakers or headphones to increase the volume, as well as mute all sound on the laptop.
If the computer should output an unusually low volume, fixing the problem may be no more involved than sliding a control switch with the computer mouse. Click once on the speaker icon in the taskbar on the lower-right corner to open a rectangular window with a slide control.
Click and hold the left mouse button on the slide control to drag it upward, increasing the volume to the laptop's maximum setting.
Click the "Mixer" button below the slider control to open another window with volume controls for "Speakers" and "Applications," adjusting each slide control upward to increase the volume.
Be sure the speaker icon below each control is not accidentally muted.
Click once on each speaker icon to remove the red circle with a slash through it, which will restore audio.
Click the Microsoft flag or "Start" button in the lower-left corner if the shortcut speaker icon is missing from the taskbar.
Click "Control Panel" to select "Adjust Sounds" from the Hardware and Sounds category.

hi when we say volume control its mean you are controlling the sound level volume of particular audio usually used a potentiometer (resistor ) to have a volume control in particular unit.hope this information help you good day.

maybe you selected the wrong sound driver. go to control panel. go to sounds, speech, and audio devices. go to sounds and audio devices. go to audio. sound playback, check the device and if diffrent change it and see if that works.

your main volume on all channels where droped. some applications can cause this to happen.
go to start. all programs. go to accessories. go to entertainment. volume control. ensure the volume is up on there. Then if it has it on your volume controll. click on speaker volume that is over top the main volume controll. and make sure your computer speakers didn't drop volume.

make sure the mute is not checked

you might want to look into one of two options... either an external sound card, or a keyboard that has mltimedia buttons on it.

If you go with the former, the Audigy 2 NX external sound card might be want you are looking for. It's small and has volume controls right on the top. Granted, it is overkill if you just want simple volume control. However, if you don't have a high-end sound card already, it could be a nice addition to your desk..?

volume control is normally located on the bottom right hand corner beside the clock, just double click on the speaker icon and you should be able to adjust the volume.
