A:Answer Yes, you can connect the Amazon Echo (4th Gen) to a Samsung TV using Bluetooth and use it as the TV speaker. To do this, you'll need to pair the Echo with the TV via Bluetooth in the settings. Once connected, the audio from your TV will play through the Echo speaker. Keep in mind that sound quality might vary, and some features, like Dolby Atmos, may not be supported when using Bluetooth. But for regular TV audio, it can work well as an alternative speaker.
