In the Line-In settings for the Room, set Autoplay to On.
There is an Autoplay option buried in Settings, which should switch to it as soon as it gets a signal. However it does cause the speaker to sleep after a while, which means it will “miss” the very beginning of the audio when it starts up.
Where are the Line-In setting for the room? I am using version 11.1 of the Sonos controller for Windows. I found lots of setting information, but I can’t seem to find that one.
Thanks,
Rob
You need to use a mobile controller.
- Open the Sonos app for iOS or Android.
- From the Settings tab, tap System.
- Choose the product you have a Line-In device connected to.
You can adjust the following settings under the Line-In section of your product’s settings:
Choose an Autoplay Room to automatically play Line-In audio when Sonos detects a signal is being sent to the Line-In port.

Thanks. That would explain why I can’t find it. I will try that later when I’m home.
