Get me:
DISPLAY =:0 /usr/lib/xbmc/xbmc-xrandr | pastebinit

and of course you have to turn on "Video -> Playback -> Adjust Refreshrate to match video".

And don't cut logfiles ...

so turning on "adjust display refresh rate to match video" to On start/stop or Always seems to select the correct modeline. unfortunately the audio dropouts are still present.

Code:

Choose Sync Playback to Display and select "Audio Clock" - just for fun. And provide a full and complete link to a debug log (paste.ubuntu.com).

adjust display refresh rate to match video: off
sync playback to display: on
a/v sync method: audio clock

audio dropout a couple of seconds before I stopped playback (line 2415)

No.

Turn on Adjust Refreshrate to match video again, having 23.976 running at 60hz is just not fine - google pulldown correction.
Your xbmc vdpau installation is quite old - use the frodo version from the wsnipex ppa and retry.

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:

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

I hope this can be of some assistance.

Do you only copyd my xorg.conf or changed the display devices to the one you are using?

Still no 23,976 mode used...

PLEASE check your xorg.conf (correct Display devices). In your case it is DFP-0 but i mentioned this before... you cannot just copy my xorg.conf becaus in my case it is DFP-1 and not DFP-0

And update your xbmc version...

wapcaplet · 2013-05-22, 23:20

I had planned to get 3 sets of logs for each combination of audio sync and refresh rate setting. But I ended up going to bed instead Smile

the only time the 23,967 mode was active was when I had the refresh rate setting turned on. Even the TV changed modes.

Interesting note about my vdpau version. I will try find some time to look into that tonight.

I appreciate your help guys.

Still no 23,976 mode used...

PLEASE check your xorg.conf (correct Display devices). In your case it is DFP-0 but i mentioned this before... you cannot just copy my xorg.conf becaus in my case it is DFP-1 and not DFP-0

And update your xbmc version...

Hi John,

I did do a direct copy of your xorg.conf. So I didn't check the DFP-0/1.

So I thought this line that came out did mean it was at 23,976

Code:
<mode id="0x1c9" name="1920x1080" w="1920" h="1080" hz="23.97610" current="true" preferred="false"/>

So turns out the config i was using was using DFP-0.

at the moment i'm in the middle of installing from wsnipex. So I'll see how that goes

oh sry, my fault... yes that means that the 23,976 modeline is active.

just a quick update,

I had to leave DTS-MA disabled for the moment, even after having the correct refresh rate running and using the updated wsnipex build I was still getting the audio glitch.

When I get a chance I might do a fresh xbmcbuntu install (my current system has been an ongoing upgrade since version 10 or something). And see how that goes.

During the last days some significant changes concerning Audio Engine were pushed to master. We now have correct buffert, transcoding, output times - so Delay is calced correctly. Additionally Renderbuffering has been merged. Backup your profile and see if the nightlies improve it.
