I have no sound in Hearthstone even if I try to change the settings
Make sure your speakers or headphones are turned on and properly connected to your computer's sound device. For specific instructions, contact your computer's manufacturer.
Swap your audio cables with a working set to test for a bad cable or connection.
Sound from your speakers may be redirected if you have headphones plugged in. Disconnect your headphones to resolve this issue.
Check your system volume by clicking the volume icon in your Windows system tray (near the clock). Make sure volume levels are set appropriately and that Mute or Mute All is not selected.
Check your in-game audio settings in the game's options menu. Make sure Enable Music andEnable Sound are checked, Master Volume is set appropriately, and your Output Device,Speaker Setup, Sound Quality, and Sound Channel are correct. Note: Higher Sound Quality settings will sound better, but may reduce performance.
