Amp V4 StandBy

Hi.
i have an Amp V4 since a few Hours :slight_smile:
Use it with LMS (AirPlay Bridge Plugin) over Ethernet, which works fine. No Speakers connected at the Moment
But if i stop the Music the Amp4 doesn´t go in Standby, Power is about 3.2W ?
I read the Amp4 goes to Standby after 10 Min…
