I use a Connect:Amp attached to a turntable to play vinyl throughout the house (love it). Autoplay is really convenient for this, since I can just put a record on, and it will play in the entire group. However, I've had to disable autoplay because it's too sensitive, and will sometimes switch over to the turntable input spontaneously, interrupting other music (e.g. from from Spotify). I suspect that the Klipsch towers in that room are causing enough vibration in the turntable's needle that it's generating *just* enough signal to trigger autoplay, or something like that.
I'd love to be able to set the threshold for autoplay (0-9 or something) with a control in the settings menu, making it less sensitive. This would make the feature usable again for me. Not sure if anyone else is having a similar problem (probably not many people), but a few developer-hours on this would be really nice
