Get a proper Xorg.conf with modelines for 23,976Hz like in my Xorg.conf

http://pastebin.com/Pyc2CGuC

Important are Modelines and the settings for Vert. Refresh and Sync...

It might be madness, but have you tried setting streamsilence to 1 ?

did noeikujoo find a solution?

As I recall, I found, but I do not remember what actually was the solution, since I have sold my previous HTPC. Sad

Nowadays I have a Xtreamer Ultra Mini-ITX HTPC, which I installed everything from scratch. I copied some configuration files from the old HTPC. HD audio bitstreams seems to work fine without discontinuities via HDMI.

Here is my current xorg.conf:

I haven't tried streamsilence I will try that tonight.

You are right about that. Some things are worth a try and not trust what is written on the internet. Reliable information is sometimes hard to find on the internet because the manufacturers website is not always being told directly what kind of audio bitstreaming the device supports.

yes. the video is playes at 60Hz... in your xorg.conf your options are for DFP-1 wich is Device 1 but you are using DFP-0 wich is Device 0. Change this and try again.

wapcaplet · 2013-05-15, 04:47

Hi John,

So when I start playing back a video at a different frame rate, should I see a change to "current" mode?

Having said that it is not only quite difficult to ascertain which cards support which formats, but also manufacturers can affect that by bad implementations.

yes.... a 23,976Hz File should use the 23,976 Hz Mode. As i said, your xrandr output says that you are using dfp-0 and your xorg.conf options are for dfp-1 so the dont aply to the device that you are using.

I have same problem as the OP on DTS-HD material too.

Proper modelines, tried streamslinece=1 and various other nonsense.

Fairly certain this is a general bug in XBMC/AE

1. The odd glitch in audio momentarily.
2. The odd 2-3 seconds where audio drops out completely then returns.
3. Happens every 10-12 minutes or so,

Seems to be a common problem on more than a few posts with DTS-HD material.

You realise that as long as everyone keeps not uploading debug logs as you do, we will not be able to find the cause.
One of the problems is that it is hard to reproduce. My systems bitstream DTS-HD MA fine because I have set them up properly .

I appreciate the response, thanks.

Please could you list the settings that need to be changed to enable proper playback without skipping/dropouts?

I will get round to uploading a log at some point tonight or tomorrow, my apologies for the blunt tone previously but I thought this was basically a known issue.

Hi John,

So I finally got around to do a bit more testing.

I dropped in your xorg.conf file and turned on debugging. here is an extract from the debug log. a couple of seconds after the audio drop out I stopped playback.

Code:
42:50 T:139902051452672   ERROR: CAESinkALSA::HandleError(snd_pcm_wait) - underrun

42:55 T:139902413649792   DEBUG: OnKey: stop (f0bc) pressed, action is Stop

I also checked the output of xbmc-xrandr and it was still at 60Hz

I hope this can be of some assistance.
