Amazon Echo aux input control stops working for older devices
Amazon has disabled Alexa voice commands for the 3.5mm auxiliary input on older Echo speakers without providing an explanation.

Voice commands no longer function
Users with legacy Echo hardware can still plug in external audio sources via the port. However, voice instructions to play or pause music from that line input will fail. An unnamed Amazon spokesperson confirmed the feature change after a Reddit user reported receiving a notification.
App settings remain unaffected
The company did not explain why this specific functionality was removed. Reports indicate that users can still access the port through the app settings menu. This update does not appear to impact other audio output capabilities for external speakers.
