Hi all,

I am building a new HPTC (replacing my 4 years hardware) using :
Motherboard : http://www.asrock.com/server/overview.as...l=C2550D4I
Graphic Card : GeForce GT 630 fanless (PCIe 8x)
CEC adapter
Denon Ceol Piccolo : sound go through HDMI out of Graphic card, then go OUT of the TV through optic fiber to the Piccolo's input

First of all, I can confirm that this configuration works pretty well with "mplayer -vo vdpau My_Holidays_movie.mkv" :
Stable picture, no sound crackling or stuttering for more than one hour test.

Important software versions I use :
- Debian Jessie
- Latest Linux 3.14.0 ('cause / is BTRFS type and I want latest improvements of it)
- Nvidia proprietary drivers NVIDIA-Linux-x86_64-334.21 (with "kernel/nv-linux.h:#include <linux/acpi.h>" modified for 3.14.0 compatibility)
mplayer Debian's version : mplayer2 2.0-701-gd4c5b7f-2

Now, the XBMC part :
I'm using 13.0-BETA4 Git:20140405-ca6c289, built on my own with :
./configure --prefix=/usr/local --enable-vdpau --disable-pulse --disable-airplay --disable-airtunes --enable-mysql --disable-optical-drive --enable-libbluray --enable-libcec

Xbmc is launched from a .xinitrc file containing only :
export XBMC_HOME=/usr/local/share/xbmc
/usr/local/bin/xbmc-standalone

Entering Xbmc, all is running fine, menu sounds too.
When playing a video first 2 or 5 seconds are good, then audio stuttering happens
When playing old Xvid files silence last for less than one second, and I can expect to have 5 or 6 "incidents" in 40/45 minutes.
But, when playing a 1080p AC3 file (same as mplayer's test), stuttering happens so much time that it is impossible to listen to.
During the recording of the xbmc.log file, links residing a the end of this post, first seconds begin to stutter, then after 2 or 3 silences no more sound output ...

I worked on this issue all the week-end, but cannot find what happens.
I definitely validated my hardware and software setup because of the successful mplayer test.

I will be pleased to give a try to Dharma release (same issue ?) but I must get my hands on the VDPAU patch needed for latest Nvidia driver version that is hanging somewhere on my hard disk ...

Thanks for your help/attention, I will be please to received hints and test what ever proposed solutions but I will be away from home for the week

Logs of a test can be found here :

Edit : Haaaaa damn me ... just realize it is not a Linux Beta thread but specific to Buntu ... can someone move my post please ?
