Hello just done a clean setup and it looks like a few extra audio settings have been added or i just didn’t see them the first time so wondered what one sends the purest signal to the Meridian Explorer 2 USB DAC from the list
Been playing around and it looks like front-Explorer2 USB DAC, USB Audio – Front speakers, CARD=DAC,DEV=O is the best option as its the only one which will light up the blue light on the Meridian DAC when playing MQA Audio but you do get the odd random crackle every now and then
