Recently, a Win7 system user reported that the sound of the computer is normal, that is, there is no speaker icon on the taskbar. Later, I went to the sound and audio device properties on the control panel and wanted to check "Place the volume icon in the taskbar", but I was prompted that "Windows cannot display the volume control on the taskbar because the volume control program is not installed." What is the problem? How to solve it? Next, let's take a look.
terms of settlement:
1、 The most likely cause: The system lost the sndvol32.exe file. The file path is C: WINDOWSSystem32. You can upload sndvol32.exe on another machine, or find a system CD to find the sndvol32.ex_ file, copy it to system32, and rename it to sndvol32.exe. Or search on the Internet and download one to the corresponding folder. Just run.
2、 Find and download the software "Repair Horn Tool" on the Internet. The software does not need to be installed. Double click it to open it and operate according to the prompts.
3、 In the control panel ->Management Tools ->Services, find the SSDP Discovery Service and Universal Plug and Play Device Host. Right click ->Properties ->Startup Type ->Disabled and restart the computer.
4、 If there is no volume control icon in the taskbar after restart, just restore the deleted item in the startup key in the registry. Start "-" Run "After entering regedit to open the registry, open HKEY_LOCAL_MACHINESOFTWARE MicrosoftWindowsCurrentVersionRun in turn to create a new string" Systray "in its right window (right-click on Run to create a new string), and the key value (double-click on Systray to edit) is" c: windowssystem32Systray. exe ".
