I have a Sonos amp connected to my computer. The line-in autoplay works to detect loud audio, but the line-in playback on Sonos stops every time the game or movie is a little bit quiet. I have to go back in to the app and press play dozens of times a movie, or gaming session.
The other option is to adjust my computer’s volume by leaving the game or movie, and adjusting the volume slider in Windows. This causes a notification sound, which triggers the autoplay. I’ve heard the last half of that audio hundreds of times a day.
Is there any way to leave the line-in playback on? If not, please send in a feature request because this is making me hate my Sonos system every time I use it.

Set the Source Level higher under the Line-In settings for the Amp in the Sonos app.
you should learn more from people who have done this well
