I’ve recently migrated my system from a pi over to a NUC DCCP847DYE running Ubuntu server 16.04. I didn’t realize there wasn’t a 3.5 output until I got everything set up so I am using this USB sound adapter: http://www.amazon.com/Sabrent-External-Adapter-Windows-AU-MMSA/dp/B00IRVQ0F8?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00. I’m running openHAB 1.8.3.
I have the audio working from the command line using mpg123, both directly from the command line and triggering it from openHAB, but playSound and playStream do not work. I see no errors in the log either and I don’t even know what direction I should be going in to troubleshoot this. openHAB is in the audio group. The only thing I can think of is maybe the USB sound adapter is throwing it off?
