As I understand it, DACs that accept I2S use HDMI cables because they have enough pins to deliver I2S differentially. The differential voltages for BCLK, LRCLK, DATA, and MCLK are needed to allow for the longer cable lengths between external devices. You would need something like a Audio-GD HDMI LVDS I2S OUTPUT Module connected to the RPi I2S GPIO pins. The HDMI output of the module would then connect to your D90. I think I have that right(?) ------------------------------------------------------------------------ mboxler's Profile: http://forums.slimdevices.com/member.php?userid=67126 View this thread: http://forums.slimdevices.com/showthread.php?t=114671
