As I watch television via DVB-T: When I select a channel is runs well for several minutes. But sometimes when there is bad signal(way to often in my area .. ) the whole video slows down to maybe 2 fps and i got no sound. If I switch channels back and forth I am fine again.

Here is a log:

I enabled live TV and the problem directly occurs. Then I switched channels back an forth and had to wait several minutes till it happens again...

I figured that it does not simply depend on signal quality... Sometimes it just shutters and I can watch on...

I have the same with DVB-S. But it also could be reproduced with material streamed over slow network. Like playing a 720p video on youtube over slow wi-fi link. The stream would pause, start buffering and never recover.

I accidentally discovered that on channels with multiple audio tracks, if the stream gets stuck like described above, switching to a different audio track without stopping playback helps recover playback.

Back with an update. I had gone to some local computer stores in hopes of grabbing a 430, but there were none to be found. Since I was impatient, I decided to risk it and picked up a cheap 610.

Results are much better, though only one problem that I'm currently experiencing. All sources play (DTS, AC3, TrueHD, DTS-MA), and HD audio is registering on my receiver. But when playing DTS-MA I'm getting a constant clicking on all sources.

Since I'm testing this out on a 610 card, the only way I could get this to work was to use the 302.17 drivers from x-swat. At this point, with the exception of the DTS-MA sound problem, I'm very happy. At least for now I can just switch to DTS.

I did rebuild the box from scratch in order to test this, starting with XBMCbuntu, then upgrading to 12.04.

I tried using this guide : https://help.ubuntu.com/community/SoundTroubleshootingProcedure#Step but the drivers still seem to stay on 1.0.24 while library and utilities upgraded to 1.0.25 just fine.

Any suggestions?

Cool.. followed the guide and even though it reports make failed at the end, it still seems to report drivers of 1.0.25 now. Will run it through it's paces over the weekend

RE: AudioEngine testers - Linux only - AbMagFab - 2012-06-22 16:17

Hi there - I've got this installed on Ubuntu, and the core functionality seems to work, but I've got two significant issues:
1) There's no hw acceleration on the video
2) The HD audio is coming through as stereo

I have it set to HDMI, 5.1, and HDMI (ALSA), and I've installed the production AMD drivers. I've tried selecting VAAPI, and even VDPAU, and nothing makes a difference. It does properly switch to 24p if I set it to match refresh rate.

I'm using an AMD E-350 with 4GB of memory. The video card is an AMD Radeon HD 6310 (which shows up properly in the XBMC sys info).

The OpenGL version that shows up is 4.2.11627

I know this card supports HD audio and video acceleration as I had the hacked Windows install of XBMC v10 for a while, and that worked fine. I just dislike Windows and would prefer to have this running on Linux.

Thanks in advance for any help!

you're going to be sorely disappointed when you actually go and read the first post to this thread...

Yeah, just saw that about ATI HD audio… Bummer.

But what about the video? Does it not support video acceleration either?

I've also got a couple Intel/ION2 systems I'm using for MythTV that I could try. I didn't think the ION supported HD audio. Am I incorrect in that assumption?

i'm not sure as i run a nvidia card. i think there is an xvba branch that brings hardware acceleration to (certain?) amd chips. edit: yup, check this out http://forum.xbmc.org/showthread.php?tid=134252

i'm pretty sure the ion2 chips support hd audio but not the ion1. someone correct me if i'm wrong.

Hi all,
first many thanks for your work,

I'm running on a Zbox HD ID11 which as ION 2 GPU. As far as I read, it's able to bitstream HD Audio.

I'm version of Frodo with AE : OpenELEC_frodo-ION.x86_64-devel-20120621180006-r11375

I tried different build as they recommend me on Openelec forum, they got different driver version. I tried
- nvidia 290.10
- nvidia-295.53
- nvidia-302.07

in my case, DTS HD/Dolby TRUE HD won't work, on the amps, the logo is blinking but no sound except sometime a 500ms exception,

I give you the XBMC log

If S.O could help that will be awsome !!
Thanks in advance

enable debug logging and try playback locally rather than over samba.
