The device is working properly and I made sure the show disabled devices are 'checked' on the playback tab.
I apologize; I sould have mentioned that these were the basic things I tried before coming to this forum after doing some research. Still no HDMI shows in the playback tab. I even updated the driver for the smart audio 221 and tried to update the audio HDMI driver but got the message that I already had the best driver. Any other ideas?
