A:Answer this thing has no analog audio output (3.5mm), so what are you plugging into what?
if you're plugging your speaker into one of the USB ports of this display, it will probably only charge that speaker
thinking that if you want audio, you'll have to get it directly from your computer (host device) by means of a 3.5mm analog connection or Bluetooth
I have a bluetooth USB transceiver plugged into my P2219H and it works fine, so you could get audio from the display to your speaker via that means, though again, you could just transmit bluetooth from your host device
finally, my experience with my P2219H: my bottom display usb ports have a (1) Asus usb bluetooth adapter plugged into one port and it works; I have a (2) Logitech Unified usb transceiver plugged into the other and it works; I've used the side ports for charging peripheral devices; I've plugged an Audioquest DragonFly USB DAC/AMP into one of those side ports and it's worked
now occurs to me - you can get a USB DAC/AMP like the Audioquest Dragonfly to get audio out of your P2219H. You'll probably want some short usb extension cables to work with the Dragonfly, thinking a 6", a 12" and perhaps an 18". I tried all those lengths and the 18" worked best for me.
