Amazon disables Alexa voice control for Echo AUX input

Amazon has officially ended support for voice-controlled management of the auxiliary (AUX) input on its Echo smart speakers. Users began receiving notifications this week informing them that commands such as "Alexa, play from line in" or "Alexa, set aux input" are no longer functional. While the physical AUX port remains on compatible Echo devices, the software integration that allowed users to switch inputs via voice commands has been removed. An Amazon spokesperson confirmed the change to Ars Technica, marking a reduction in the feature set for legacy Echo hardware. This update has sparked frustration among users who relied on voice-activated switching for external audio sources like turntables or media players. The company has not provided a detailed technical justification for the removal, but the move reflects a broader trend of Amazon streamlining its smart home ecosystem and potentially deprecating underutilized features in its voice assistant software.
