I just hooked up the mini and when i play music from the amazon hd app it shows to cast it to the mini and says it is playing thru the mini but the sound cuts out. My dac shows bit perfect but it just wont play. Amazon hd music plays fine when playing from the wiim app and shows bit perfect. Any ideas on why. I have fast internet and it streams in ultra hd fine thru the wiim app but not thru the amazon app which i prefer.
