Hi Anssi, Thanks for your answer

Test on kernel 3.8 + non-pcm bit in AES0: aplay -D hdmi:CARD=PCH,DEV=0,AES0=0x06 -c8 -fs16_le -r192000 dts.spdif => same result: no signal

Hmh, OK.

Test with a non spdif-encapsulated file extracted from blu ray which is 16 bits 8 channel 192 kHz : aplay -D hdmi:CARD=PCH,DEV=0,AES0=0x06 -c8 -fs16_le -r192000 dts.dts-hd.sample_track2_und.dts => I get a static noise and receiver shows PCM and 2 channels (front left and front right)

You can't output non-encapsulated audio directly, you need to encapsulate it e.g. with ffmpeg: ffmpeg -i file.dtshd -acodec copy -f spdif file.dtshd.spdif

With kernel upgrade to 3.9: same result

Note that I have tested with alsa* 1.025 and intel-hda driver included in kernel

Do you have any other idea?

You could try DEV=1 instead of DEV=0 (according to your log DEV=0 is correct, though), and truehd (thd.spdif from ffmpeg samples).

If neither of those work, could you provide another alsa-info while playing back using AES0=0x06 (with alsa debug enabled again)?

Thanks

Hi there,

Hi!

...

I have troubles using HBR audio (DTS-HD and Dolby TrueHD). With every test, I get no signal in the AV receiver. I have tested using a dts-hd encapsulated in spdif sample file (found there http://samples.mplayerhq.hu/hdmi/) and commands bellow

• aplay -D hdmi devices
• aplay -D hw devices
• aplay -D plughw devices

You need to set the non-pcm bit in AES0. Use e.g. "-D hdmi:AES0=0x06".

...

Note that I use ubuntu raring with 3.8 kernel that includes Xingchao's HBR kernel patches.

A. Configurations I have tested:

• hda driver upgrade (alsa devel ubuntu team daily builds)

• upgrade alsa-lib & alsa-utils (alsa-testing launchpad)

• kernel upgrade to 3.9

IIRC 3.9 (or newer) may indeed be needed since you have both hdmi and spdif.

...

• snd_hda_codec_realtek module backlist (to try to disable SPDIF)

/etc/modprobe.d/blacklist.conf

• snd_hda_codec_realtek index = -2 in /etc/modprobe.d/alsa-base.conf

• fresh new ubuntu raring install with no modifications at all: still

no signal

B. Info:

cat /proc/asound/card0/codec* | grep Codec Codec: Realtek ALC892 Codec: Intel CougarPoint HDMI

I use zotac ZBOX ID82 (intel HM65 chipset with hdmi and spdif)

with alsa debug and alsa debug verbose enabled in kernel I got the alsa-info.txt attached file produced on raring with no modification while playing dts-hd sample file with command:

aplay -D hdmi:CARD=PCH,DEV=0 -c8 -fs16_le -r192000 dts.spdif

As per above you need to use aplay -D hdmi:CARD=PCH,DEV=0,AES0=0x06 -c8 -fs16_le -r192000 dts.spdif

...

C. I add that:

• In every test I have non HD audio protocols (DTS and dolby) working

well in the same configuration

• I have tried with windows just to see if my hardware is broken and I

get DTS-HD audio with no problem

• Takashi, I've read your HD-Audio.txt file and as far as I see, I have

no known error message in kernel log

=> I and Wingchao Wang have conclued that it is driver or codec related. Can you help me please?

Thanks a lot PS: sorry if you receive this email twice, I have sent it again as I was not member of the list the first time.
