Setting the values to 48,000 Hz was required by the application. I could not set it to 44. Would get error message. It is easier to set all of them at once rather than going down the list. For what I am doing - Redbook it made the most sense. In reality it only does a couple anyway because it doesn't go higher than that. How you want to set things is up to you. I would experiment. There are many menu choices, I recommend going through all of them. I am showing some of the ones that I think should be considered. Trying to think of things that might make a difference to the original problem. You definitely want to go to device settings and find the driver that works best for your DAC. There should be a list to pick from. Then check these settings. Maybe you need to alter Buffering.
