Hello Anthony,<br /><br />Thank you for taking a few moments to review the HW-B620F Samsung Soundbar.<br /><br />If available, we recommend using the HDMI connection to your TV. <br /><br />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.<br /><br />There are a few things you may want to check:<br /><br />1) The maximum wireless signal transmission distance is about 33 ft. <br />2) Electronic devices may cause radio interference. Devices that generate electromagnetic waves should be kept away from the Soundbar main unit - e.g., microwaves, wireless LAN devices, etc.<br />3) Also, please be sure you have the latest firmware update. You can update your firmware by Auto Update, using the SmartThings app, or by using a USB device. You can find the update on the product page of your HW-B620F on the Samsung website.<br /><br />Should you need further assistance with this issue or have any questions about features or operation, please know that Samsung is here to help.
