Why did my laptops sound stop working?

Question

My computer had a virus and I sent it in to get repaired. When it came back the sound stopped working. When I go into control panel and sounds it says "no audio device". What happened and how can I fix this?

Answer 1

They probably re-installed Windows - and without access to the sound drivers for your system -these will have been omitted - you need to reinstall the soundcard - if you have a CD you can do it from that - if the PC didn't come with one or you don't have it - you'll need to find the driver on the net - in which case you will need the manufacturer of your sound hardware.



Goto Control Panel - SYSTEM icon - HARDWARE tab - DEVICE MANAGER button - click the PLUS sign next to SOUND AND VIDEO controllers - this will clue you in to who makes your soundcard - could be something like REALTEK AC97 or some such name - Google "Realteck AC 97 sound driver" or whatever your sound system is called.



Download the driver (if you cannot find it - check with Driverguide.com or Download.com or other sites)



Run the install package - this should put your audio device back into commission.

Answer 2

First try rebooting the computer...that fixes 90% of the problems..



Try one of my fixes below to get your audio working again….



Make sure the speakers are plugged into the green jack. Also make sure it securely plug in and powered (If amplified).



To Display The Volume Icon

By default, the Volume icon is not displayed when you initially installed on your system.



To enable the display of the Volume icon, follow these steps: 1. Click Start, and then click Control Panel.

2. Double-click Sounds and Audio Devices.

3. Click Show volume control on the taskbar.

4. Click OK.

When you have the new desktop features enabled, follow these steps: 1. Click Start, and then click Control Panel.

2. Click Sounds, click Speech, and then click Audio Devices.

3. Click Sounds, and then click Audio Devices.

If that doesn't work then try this.

Then go to "Tools"..."Manage Add ons"...and make sure everything is enabled.



Then close Internet Explorer and reopen



or

If your computer is a clone, you will need to remove the cover and copy the model number of your motherboard or soundcard (if you have one) and do a search online with the model number.

Answer 4

It's possible that if they took your laptop apart at all then they could have damaged a sound wire, though I'm not sure. I suggest taking it back to the people who 'repaired' it and ask them about it.



Gp.

Answer 5
