Hello Couldbebetter, We appreciate you taking a few moments to review the New Samsung HW-QS700F Soundbar. If you leave the soundbar on a different source (e.g., HDMI), it may not auto-switch back to Bluetooth. Make sure you leave it on the Bluetooth source before turning off the TV. If available, we recommend using the HDMI connection to your TV. Connecting your soundbar to a TV through HDMI will provide the best audio and user experience, often eliminating any connection or delay issues you may be experiencing. There are 2 ways to connect your soundbar with HDMI: you can connect a device to your soundbar (like a Blu-ray player) and then connect the soundbar to the TV, or you can use HDMI ARC. The first method will give you the best possible sound from external devices you regularly use. ARC is the way to go if you want great sound from streaming apps on your TV and a soundbar. If you need more help, Samsung is here for you. Please call us at 1-800-SAMSUNG, 8AM - 12AM EST (Ask for Soundbars), 7 days a week. Our Live Chat agents are also available by clicking on the ‘Support’ link on our website. ~ Samsung Solutions
