There is no way to use both PC and share the SB521A Soundbar. See the online P2422HE User's Guide pages 11 and 12 for port numbers. See the online SB521A Usage and Troubleshooting Guide = Note: Ensure you are connecting the correct USB uplink cable between your monitor and your computer by checking your monitors manual. Both P2422HE #7 USB Type-C upstream ports have to be connected to both PC with the additional USB-C to USB-C cable or USB-C to USB-A cable. That turns on both P2422HE USB downstream ports.

Hi, I've just purchased two Dell P2422HE monitors and the SB521A Soundbar. I can't get my monitor to recognize the SB521A Soundbar at all?  It's not on the Device Manager and I don't know how to set it up? I've tested the USB ports and they seem to be working. I've tested the SB521A Soundbar by connecting it to my laptop and it works. The problem seems to be that my monitor doesn't recognize it. Any ideas or help would be appreciated, as I'm guessing this should have been the easiest bit of my set up.   The way I've got my set up is as follows = I've tried the SB521A Soundbar on both P2422HE 1 and P2422HE 2.
SB521A Soundbar, set up with dual P2422HE?
