I upgraded to Version 26.82 and no sound. I tried turning my DAC on and off. I pulled the cables off and reinserted. I rebooted the computer. Nothing. I checked all the MC settings for Audio path. All OK. Then I tried routing sound from my computer through the DAC - and again - NOTHING. So it wasn't the MC. It must be the DAC. I pulled the DAC manual and checked the settings. All OK. Out of the blue I decided to check my receiver volume and I am embarrassed to say the volume was too low to hear.
I'm going to go pout somewhere.
