I own a D54250WYK since one month. When playing movies (1080p mkv's) I notice slight stuttering. Other people don't notice it, but I do. When I compare the smoothness of video playing with the Boxee I used before, then my upgrade was not really an upgrade.

Don't worry, you're not the only one who is allergic to frame drops and skips. With correct settings, you can get very good output from your NUC.

My setup: I hooked up the NUC with HDMI to a Yamaha YSP-3300 soundbar (7.1 and capable of all passthrough options). The soundbar is connected to my TV (Philips 46PFL8008). My movies/tv shows reside at a Synology DS213+. Wired connection. (connection is not the issue: the Boxee works fine) All new gadgets.

I use the Openelec nightly builds (Generic.x86_64-devel-20131212104328-r16530 at the moment) with Aeon MQ5. I performed all kinds of different settings to get rid of the problem:

- enable / disable VAAPI
- enable / disable audio passthrough
- "Adjust display refresh rate to match video" enabled / disabled
- sync video to audio -> tried all different settings
- different refresh rates (currently @ 60fps)
- accessing NAS via smb and NFS (currently NFS)

Everything I bought should be up to the task, but I can't seem to get rid of the mini-stuttering. Anyone got suggestions which settings are optimal in my situation? Or maybe suggestions how to tackle the problem? What can I do to determine the source of my problem?

Put a movie on local NUC storage to eliminate the network. Use xbmc-xrandr to check that all the video modes are detected correctly.

In video playback settings, set render method to auto, enable VAAPI, adjust refresh rate on start/stop, sync playback to display, set a/v sync method to video clock (drop/dupe audio).

If you still see stutter, look into the logs.

Ok, i just logged the HD-Audio Problem and uploaded it here :

FYI what i did :

Started Debugging
Restarted XBMC
Went to Systems / Settings / Video and enabled "Adjust display refresh rate to match video"
Then started "Star Trek: Into Darkness" -> NO SOUND
Started another Movie "The Avengers" heavy stuttering and freezing, no Sound again.
Uploaded the Log

To get the HD-Sound working again i need to disable "Adjust display refresh rate to match video" and restart.

So i made the log hope someone can get a clue of the problem or tell it the right guys as i have no clue where to post this else...? Maye i should send it Fritsch, at least he is talking my language

@ lmyllari

Sent u a pm, maybe u can get into this once again

Thanks for the log. You should also capture a kernel log, since this is a driver issue - xbmc just sees that it becomes impossible to write audio to the output. I posted some instructions earlier in this thread - see http://forum.xbmc.org/showthread.php?tid...pid1571160


edit: please note that you need a special build with audio debugging if you do this
