No audio output device installed after installing windows 10 from linux SF315-52G

csaba591

My laptop, which I purchased a couple days ago, came with Linpus Linux, so I decided to install Windows 10 on it which I've already activated.

Everything went fine except for driver installation. There is a partition called "WINDRIVER", which contains all the drivers and acer software that need to be installed. It also has an autorun file, so I assume the installation of these should have been automatic. Since this didn't seem to happen I started installing the drivers manually and most of them, I could, except for the Realtek Audio Driver ALC256M

So the problems I'm currently facing are:

1. the sound icon in the bottom right corner says: "There are no audio output devices installed."

2. I can't install Realtek Audio Drivers because there is no audio output device in device manager.

Hi csaba591,
  Please follow these steps to fix this.

 Re-enable the device 

To fix the problem, follow these steps (Steps below are for your reference. The specific steps in different system versions may be different. ):

1) On your keyboard, press the Windows logo key  and R at the same time to invoke a Run command. Type devmgmt.msc in the run box and click on OK button.

2) Locate the Sound, video and game controllers category in the list.

If you don’t see this category in your list, continue with step 2a) below. Otherwise skip to step 3.

2a) Click the Action menu and select Add Legacy hardware (if you see only the Help in this menu, click somewhere in the white space around the list (i.e. make sure nothing in the tree is selected), then click the Action menu again)

 

2b) Click Next to start the Add Hardware wizard. (If the Add Hardware wizard doesn’t display at all, skip to Method 3 below.)

2c) Select Search for and install hardware automatically (Recommended).

2d) If the wizard tells you it can’t find any new hardware, click Next.

2e) You should now see a list of hardware types. Scroll down until you see Sound, video and game controllers. Select it and click Next.

2f) Select the manufacturer and model of your sound card, then click Next. (If you’re not sure what manufacturer and model to select, skip to Method 3 below.)

2g) Click Next to install the device, then when the installation is complete, click Finish.

 

3) Expand the Sound, video and game controllers category, and right-click on your audio device. Click Enable in the pop up menu. (If the device is already enabled, skip to Method 2 below.)

 

Method 2: Manually uninstall & reinstall the device driver

1) Still in Device Manager, once again expand Sound, video and game controllers, right-click on your audio device, and click Uninstall to uninstall the driver.

2) Restart your PC. After restarting, Windows should automatically re-install the sound driver. Assuming it installs the latest correct driver, this may resolve the problem.

Method 3: Automatically update your audio device drivers

Your sound problem is probably being caused by driver issues. The steps above may resolve it, but if they don’t, or you’re not confident playing around with drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

2) Run Driver Easy and click Scan Now. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to a flagged audio driver to automatically download and install the correct version of this driver (you can do this with the FREE version). Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

 

Please let me know if this fixes your issue.
