The audio comes from the PC through either HDMI, DP, or USB-C. The PC audio is then routed to the two built-in 9W speakers. The rear Audio line-out port is only for powered external speakers. * Open the U4021QW Menu--> Audio* Speakers = On* Exit the Menu* Right click the Speakers icon on the right taskbar* Click, "Open Sound settings"* Under, "Choose your output device", click the down arrow and look for U4021QW Audio* Choose that as the default output device
Hi there, I hope somebody can help me out on the issue. The U4021QW is only a week old, I love everything about it. Just this morning when I started it, I noticed there is no sound coming from the speakers.  I have checked the connection, reinstalled the drivers, checked the control panel settings, sound output, nothing.  This is a bit bummer. I am running on Windows 10, all drivers updated. This is strange, also there is no input connector on the back of the monitor.  Thanks in advance.
