Hi guys,
For those who have dts-hd working, could you please kindly do the DTS-HD test bellow for me?

1. Enable alsa debug in kernel (recompile from sources) as Xingchao shown and reboot on the new kernel

2. Download dts-hd sample file

3. Add the following to ~/.asoundrc:
Code:
## begin custom stuff
pcm.hdmihdtest {
        @args [ DEVICE CTLINDEX ]
        @args.DEVICE {
                type integer
        }
        @args.CTLINDEX {
                type integer
        }
        type hooks
        slave.pcm {
                type hw
                card YOUR_CARD_AS_IN_APLAY-l
                device $DEVICE
        }
        hooks.0 {
                type ctl_elems
                hook_args [
                {
                        name "IEC958 Playback Default"
                        index $CTLINDEX
                        lock true
                        preserve true
                        value [ 0x06 0x82 0x00 0x01 ]
                }
                {
                        name "IEC958 Playback Switch"
                        index $CTLINDEX
                        lock true
                        preserve true
                        value true
                }
                ]
        }
}
pcm.hdmihdtest0 { @func refer name "pcm.hdmihdtest:DEVICE=3,CTLINDEX=0" }
pcm.hdmihdtest1 { @func refer name "pcm.hdmihdtest:DEVICE=7,CTLINDEX=1" }
pcm.hdmihdtest2 { @func refer name "pcm.hdmihdtest:DEVICE=8,CTLINDEX=2" }
pcm.hdmihdtest3 { @func refer name "pcm.hdmihdtest:DEVICE=9,CTLINDEX=3" }
## end custom stuff

4. Make sure alsa is not muted with
Code:
alsamixer -cYOUR_CARD_AS_IN_APLAY-l
5.
Code:
aplay -D hdmihdtest0 -c8 -fs16_le -r192000 dts.spdif

6. run alsa-info.sh script and paste the output text
