I went to a machine that was a clean install of 10. Version 1607 that is now 1709.
Both were set to no sound.
You wanted to know default so I went to a clean machine that I know I haven't changed.
The default is none and they make no sound.
If you want sound on those things, Take the drop down menu under Sounds and choose a sound you want, and test it. You can also press the Browse button and choose any of the sound folders and choose the sounds in there.
