Hi there,

I am using the Edifier R19u USB speakers with a mid-2010 iMac. After updating to MacOS Sierra, the system no longer detects the speakers and I'm now unable to play any sound through the external speakers. The sound is playing thru the internal speakers instead.

Any fix for this?? HELP!

Do they show up in the USB Device Tree?

Another question:
Are the speakers connected directly to the Mac's USB port, or are they running "through a hub" ...?

My secondary display stopped working with sierra. (I suspect that this might have had something to do with airserver). Didn't even show up in the System report. Had to reboot. The display came back. Yay. Now I can watch TV and do work at the same time.

I've rebooted many times. I've even tried resetting the SMC & NVRAM, still nothing.
