when i try to play any video or audio on the laptop the volumn suddenly fades away i.e the volumn becomes low but the speakers volumn bar remains the same dosen't change the position. If i pause and then play the audio file again then for some seconds the sound comes back to orignal volumn then again fades away. This has been happining a lot.
Into the Run window, type devmgmt.msc and hit enter.
In Device Manager, expand Sound, Video and Game Controllers. Right click the Realtek device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, download and reinstall the Chipset driver on the following link.
When the Chipset reinstallation has completed, restart the notebook.
When windows has reloaded, open your Downloads folder, right click on the Realtek installer and select 'Run as Administrator' to start the installation. When this has completed, restart the notebook again and let windows fully load for a few minutes before checking.
