Try to repair osu!

In the wise words of Kao
Here are steps you can do to repair osu!
Method 1: Launch Repair Dialog

1. Hold down the Shift key on your keyboard.
2. While holding Shift, double click the osu! icon on your desktop.
3. Continue holding Shift until you see the recovery dialog prompt.
4. From there, click on the "Repair osu!" option

Method 2: Shortcut
If you have the "repair osu!" Shortcut, opening that also works.


Method 3: Config Shortcut
If you don't have the "repair osu!" Shortcut, you can create one instead.

1. Right click osu!.exe > Create a shortcut
2. Open properties of the shortcut
   
   1. Select then Alt + Enter or
   2. Right click > Properties
3. Set Target to ...\osu!.exe -config
4. Press OK then open the shortcut

Method 4: Text document
You can also force the updater to run by creating a new text document in your osu! folder called "help". Right-click in an empty space in your osu! folder, and choose New > Text Document.

SPOILER

Name it help and then run osu! to start the updater in forced maintenance mode.

Right click the sound icon at the taskbar and click on "Playback Devices"
Which do you see as default? If it isn't Speakers or Realtek
Right click on it and click on "Set as Default Device"


It should show that speakers is set to "Default" after you've done it


After that, restart osu!

1. Click on “Start” > “Control Panel”.
2. Under the Control Panel, select “Sounds and Audio Devices”.
3. Click on “Audio” tab.
4. Under Sound playback > Default device, select Speakers
5. Click on "Apply" followed by "OK".
6. Restart the computer.
