# SAMPLE
In the relevant scenario, the **Sound** block is triggered to play when a signal is received from the digital input. To ensure continuous playback when the contact is made, the condition **"If comes 1, send 1"** must be assigned to the output of the digital input. Without this, the sound would stop as soon as the contact (ring button) is released.
The **Sound** block also offers various playback options, such as playing for a certain duration, playing once, or playing continuously.
