Amazon kills Alexa’s ability to control Echo speakers' AUX input

Amazon has removed the ability to control Echo speakers' AUX input through Alexa, a feature previously available on the smart speakers. This change is likely due to the lack of 3.5mm ports on new Echo models, with the last Echo device to include this port being released six years ago. The AUX input control feature allowed users to play music from external devices through the Echo speaker.
