Answer 1

Just define a style that plays the sound on the event PreviewMouseDown:

<Style TargetType="Button">
    <Style.Triggers>
        <EventTrigger RoutedEvent="PreviewMouseDown">
            <SoundPlayerAction Source="/ClickingButton;component/click.wav" />
        </EventTrigger>
    </Style.Triggers>
</Style>

See here for a discussion on why not to use Button.Click event in the event trigger. Basically, the problem is, that the Button.Click event is a bubbling one and the event trigger will be executed after the code in your normal click handler executed, i.e. the sound will have a delay, if your event handler does something that takes some time.
