@PeterV:
Normally aticonfig is just a symlink to amdconfig or the other way round - so both should work.
What does: ls -l `which aticonfig` tell?

Best is to upload a sample, pastebin your xbmc.log with debugging turned on (complete one) and describe the error you are seeing.
Thanks - will do this. I think I've narrowed it down to x264 files with FLAC 5.1 audio tracks. They either exhibit this skipping back to previous frames from the get-go, or on the second run. Once it's happened, it affects all files that are decoded using xvba until X & fglrx are restarted.

I'll cut a couple of the files down to a minute or so and paste a log when I get a chance.

I've tried all of that but still no improvement. I'm thinking about a fresh installation of the system, since this problem occured without any config changes done by myself.

Just to let you guys know: I did a fresh installation of Ubuntu 12.04 LTS Minimal while following the steps on page 1 and the problem hasn't occured yet. Thanks for the detailed step-by-step guide.

There might still be issues with broken 4.1 content that actually should be decoded as 5.1 content... with the va driver if you have the 5.1 support enabled, you could fix it with this patch... I suspect that a similar patch could be worked into this...

Code:
diff --git a/src/xvba_buffer.c b/src/xvba_buffer.c
index 4facbbf..d8012a3 100644
--- a/src/xvba_buffer.c
+++ b/src/xvba_buffer.c
@@ -368,23 +368,18 @@ translate_VAPictureParameterBufferH264(
         obj_context->picture_height
     );

-    /* Check for H.264 content over HP@L4.1 */
+    /* Check for wrongly coded H264 Level 41 files
+       adjust profile to Level 51 when reframes are too many
+     */
     unsigned int num_ref_frames = pic_param->num_ref_frames;
-    if (profile == XVBA_H264_HIGH && level > 41) {

         const unsigned int mbw = pic_param->picture_width_in_mbs_minus1 + 1;
         const unsigned int mbh = (obj_context->picture_height + 15) / 16;

     }

@dandel:
Thanks for posting my own patch. This is for the xvba-va-driver. This one has absolutely nothing to do with our xvba branch. xvba-va-driver is a wrapper that translates vaapi to xvba. So applications that do not have direct xvba support can use vaapi and are therefore translated to xvba.

xvba-va-driver is not maintained since over a year - though i am planning to push in mpeg-2 and mpeg-4 support when they are available.

I just installed following the steps in post 1. And now I am getting the same old problem. If I turn off my tv and have it off and start it later then I have no sound.
i have to reboot my xbmc pc to get the sound back. Then everything works just fine until I turn the telly off again. I love xbmc but hate this problem.

Is there any work around for this? Below is my amd card from lspci.

@laric:
Upgrade to fglrx 12.6. This should fix the hdmi sound issue. See: http://forum.xbmc.org/showthread.php?tid...pid1138272

Thanks for the wonderful suggestions to install XBMC PVR Xvba. I didn't have any problems following the guide. I have a few questions though

1. If I need to just install XBMC Xvba instead of XBMC PVR, what repository I need to use in Step 3

2. Also if we follow the steps in Page 1, does it come with fglrx 12.6 or do we need to follow the above link to install it?

@Just4U:
2. Nope. fglrx 12.6 is not installed by default, as AMD stopped supporting some devices HD2XXX, HD3XXX, HD4XXX. You can use the above instructions to update fglrx, if your video card is supported. If the original version works for you, keep it.

1. Our direct upstream is xbmc-pvr. So all of our versions include PVR. You can easily disable everything PVR related within xbmc - so it does not harm.
