I have a HP 650 G1 laptop, and have just updated the Win10 install to the latest Anniversary update.
After doing this, my "Audioquest Dragonfly USB DAC" sounds terrible. So bad I cannot actually listed to it.
The dragonfly has no drivers, as it uses the default Windows USB Audio device driver. Which from looking at Device Manager was updated on the 15th July 2016.
Other than rolling back and hoping that it works, is there a fix, or an alternative driver I can download ?.
