Sogou input method is OK, but 4 conditions need to be met

1. Upgrade Sogou to version 7.9 or above

2. Turn on the ringtone volume

3. Use a skin with a sound effect logo (you can ignore this if you only want the key sound)

4. Click the input box to pop up the Sogou keyboard, enter the S icon on the Sogou toolbar, click the key sound effect, and turn on the key sound.
