I am only wanting to do this for listening to my lossless audio files on my external hard drive. I have Jriver on my laptop. laptop has USB port and HDMI port AppleTV 3 is in the mix because the Anthem D1 has no HDMI port only digital optical toslink input and single XLR digital input. so I am trying to run the music from laptop to the appletv3 optical output to the anthem D1 digital input. not sure what I need to do first. this is just for music but I am trying to do it without going from analogue to digital and then back to analogue again. less back and forth converting.
