RE: AudioEngine testers - Linux only - wxc200 - 2012-08-13
from your log i found the HBR bits were "0", meaning the High-bit rate features was not working at least in GFX side. it's what i'm confusing now.
AUD_OUT_STR_DESC_A HBR_enable 0
AUD_OUT_STR_DESC_B HBR_enable 0
AUD_OUT_STR_DESC_C HBR_enable 0
RE: AudioEngine testers - Linux only - Fneufneu - 2012-08-16
hi,
i have an issue when i try to play TrueHD decoded into LPCM (disable truehd support and enable lpcm)
all works fine except the center channel, i have no sound at all from it.
i checked (with dolby truehd channel check 7.1) and all channel are mapped correctly, except the center.
i dont known if it's ffmpeg or anything related.
my system: FreeBSD + OSS + ffmpeg 0.11.1
also can someone plz pastebin a log of hd files (dtshdma and truehd) successfully played with alsa on a receiver who support it.
i need to make some diff with my OSS log output.
thanks !

ok i found my problem, LFE and center channel are inverted

i fixed TrueHD decoding channel mapping in ffmpeg 0.11.1: http://fneufn.eu/freebsd/patch-libavcodec-mlpdec.c
can someone confirm if it's works correctly on ALSA without my patch
and i'll send issue in upstream.
RE: AudioEngine testers - Linux only - fatal. - 2012-08-19
Hey,
I am using the latest OpenELEC generic build by ericab (r11809 - Frodo-r16812)
On some DTS-HD tracks I am getting a lot of "crackling" when there is a loud sound effect/explosion. This only happens on my htpcs connected to TV and XBMC is set to output using HDIMI with 2.0 speaker configuration (everything else is turned off). I've tried this on 3 different tvs.
Playing the same movie/section while bit-streaming to the receiver everything plays fine, no crackling. Also playing it on my desktop with headphones using MPC also has no issues.
Here is a sample video for which I get crackling: http://www36.zippyshare.com/d/27144396/7782813/dts-hd.sample.mkv
Debug Log: http://xbmclogs.com/show.php?id=6895
Using GT430.
Take Care

Bug in audio player
Hello,
i use Xtreamer Ultra 2 and i found bug in OpenELEC_frodo-Ultra.x86_64-devel-20120820113649-r11814...idia-v304.37.tar.bz2 audio player. When I play DTS audio file in wav format the time go fastly, but the song sounds good. Then the audio file ends before. MP3 works without problem. Movies play correctly.
Try pls this wav file. share-rapid.com/stahuj/d5880qm1 . Another problem is that album art in DTS wav files is not display correctly.
In OpenELEC 2.0 Beta 6(1.95.6) is everything OK. DTS wav files plaing correctly and too the album art in files are displayed correctly.
Thanks for answer.

Thanks your test. I have one Yamaha RX V571 which supports HBR stream testing now, so i can test my patch easily. About the patches, i used name "xingchao.wang@Intel.com".
Currently one clue is about HBR bits setting, another one is about N/CTS programming. Intel driver left the default values for TMDS clock and the HDMI spec has requirement to program N/CTS according to ASP type. There's one recommended talbe for various rates and TMDS clock(according to HDMI SPEC 1.3a, table 7.1). I'm doing more test based on that. I know little about the knowledge on this and how does that work on the enabled-HBR platform such as Nvidia's card. if anyone can share with me some infomation, i will appreciate that much.
thanks

I have a similar problem. Any DTS-WAV file with cue sheets are not playing properly. Some dont start where they should and always cut out early.
RE: AudioEngine testers - Linux only - wxc200 - 2012-08-28
The HBR stream could work on Intel's chip now, i will update the patch later.

I didnot find there's attachment option, so i just paste the patch here.
please apply the patch against Takashi's latest sound tree.
i tested this patch on my Yamaha A/V Receiver, both DTS-HD MA and Dolby TrueHD HBR streams
could play well.
Please note this patch is only for test purpose now, it's not the final upstream version.
There's another dependent hack from Anssi, please apply the second patch against Takashi's alsa-lib tree.
If there's any problem during your test, please feel free to let me know:
xingchao.wang@Intel.com
[PATCH] ALSA: HDMI - Enable HBR feature on Intel chips
HDMI channel remapping apparently effects HBR packets on Intel's chips.
For compressed non-PCM audio, use "straight-through" channel mapping.
For uncompressed multi-channel pcm audio, use normal mapping.

hi
running about a week now alpha5-commit bc0813f and i think it is the most stable until now
it is running in debian-wheezy
but i cant make 2 days now a new version running
i get xbmc built succesfully but when i try to run it with make install or ./xbmc.bin
it give error unable to create application.Exiting
i use --prefix=$HOME/xbmc --enable-external-libraries --disable-external-ffmpeg and some other options for my hw (no joystick,no vaapi,no pulse etc)
i try to configure it with default options but no go
how can i run it in verbose to get some more debug
RE: AudioEngine testers - Linux only - DDDamian - 2012-08-29
@fatal - sounds like when it's downmixing to PCM it's being clamped or limited which can cause that distortion. It may be we're not using the best downmixing ratios but also check that Settings>System>Audio Output>Boost level on downmix is turned off and see if that helps. If it was already off pls let me know.
