Hi there,
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
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
- 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
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.
