Hi, I am using a Core i5-3475S on a ASUS P8H77-I. The system is connected to my amp through HDMI. For some reason I cannot get passthrough of DTS-HD MA or Dolby TrueHD to work properly. On my HTPC with an ION2 chipset I can use aplay -D hdmi:CARD=NVidia,DEV=2,AES0=6 -c8 -fs16_le -r192000 dtshd_test.spdif and the receiver recognizes and plays the DTS-HD MA stream. On my Intel system I am trying the exact same thing (different card name, obviously) and the receiver only plays noise (shows 7.1 PCM instead of DTS-HD). Am I doing anything wrong? Are there any configuration options I am missing or kernel module parameters? I am using the latest stable xf86-video-intel driver and Linux kernel. Regards, Frederik
