Sound preferences are poorly discoverable (Theme tab)

[Chealer]

Stretchly contains some audio preferences:

Unfortunately, their location in the Theme tab makes them hard to find. While the option to choose the sound arguably makes sense in that tab, putting the option to mute there does not.

I recommend to move sound preferences out of the Theme tab (or to rebrand the tab).

This affects Stretchly 1.17.2.
