Low-clutter audio at the desk: SB521A
SB521A is a USB-powered slim soundbar designed to attach magnetically to selected Dell displays. It uses USB digital audio, so check the monitor's USB upstream connection and host routing rather than assuming an HDMI or DisplayPort cable alone will carry sound to SB521A.
