We installed a new system, the sound card driver is also installed, but found in the desktop lower right corner of the volume of small icons disappear, without this small icon is not very convenient for us to adjust the volume size, the volume of small icons disappear from the lower right corner is likely to appear in three kinds of reasons.
The first type: sound card driver is not correct
The sound card driver installation is incorrect and will not be able to see the volume small horn icon. If you have already reinstalled the driver or cannot find the small speaker that controls the volume, it is possible that the operating system did not recognize your sound card model, you must install the corresponding sound card driver.
The second type: System auto-Hide
The system sometimes automatically hides some infrequently used icons in the taskbar. Just right-click on the taskbar, select Properties, click the Taskbar tab, remove the hook in front of the Hide inactive icon, and then see the small horn that adjusts the volume.
The third type: improper system setup
If you are sure that the sound card driver installation is correct, it is possible that you did not set the system to put the volume small horn icon into the taskbar. You can go to "Control Panel", double-click "Volume and Audio Device", select the "Put the volume label in the taskbar" front of the hook, click "Apply", should be OK.
