A:Answer Thank you for a great question on our SmartCast™ SB4551-D5!
This soundbar can play music via a USB drive, but the drive will need to be formatted to FAT32, and the music must be in .WAV format. Outside of this, you can connect audio device with Optical, Digital Coaxial, 3.5mm, RCA (red/white), Bluetooth, and through Google Cast.
If you have any questions or concerns, we encourage you to reach out to our Support team at 844.254.8088. Thanks again and have a great day! -Collin
