Thanks to all. I wish i had good news to report. I read all your responses and suggestions, and appreciated your time, My wife and I uninstalled Audirvana, and then reinstalled same. No issues on either end. However, Would load the music and show icons of albums just as expected. Then hit play a particular song and the timer would start, but, no sound. My wife who is more schooled in computer things than I, explored all sound settings in Audirvana and within all computer settings. Tried just Quboz via USB, played perfectly and sounded great as usual. Must be a glitch somewhere, so close, you know the rest. I bought my Bricasti from Verdant Audio in NJ. I called him yesterday, and he was so helpful or tried to be( for over an HOUR) It was so nice to speak to a human (caring one) for the interaction. He suggested what most of you did. I would love to stay with Audirvana for the sound,but, with NO human interaction to fix my issue I cannot, what a shame. I know it would cost more money for an 800 number, but they are going to lose a subscriber, maybe they don't care? (CUSTOMER SERVICE IS SO IMPORTANT TO ME) I don't know? Roon may be my next experiment, Or may just stream Qobuz/USB with my rock and roll. A waste of a Network card though!!!! A simple walk through on the phone with a dedicated tech, would most likely solve the problem. Again thanks to all who took their time to help. Robert TN
