Thank you everyone! I'll try a complete shutdown of my N150 to see if that helps. I've already tried a shutdown, delete and reload of Conductor 4 with only minor partial success. I should add that I had been listening to Internet Radio for over an hour then cleared the queue and loaded a very long Qobuz playlist. It was almost 5 hours long and that's when I started adding more problems above.
I did contact Aurender Support on Thursday night (PDT) when the problem started and haven't heard back from them. But if they are in Korea it's been weekend for them.
I will update this thread. Thank you Audiogon and the Audiogon Community!
