Sound lag after some minutes

Hi everyone,

I have an issue when I play videos. After a while (between 5 and 10 minutes generally), the sound start to be jerky, and I have to stop the video, then start at the same point and no more sound issue.

It happens with 1080p and 720p.

I have an intel NUC, with an i3 and HD Graphics 3000.

My videos are on a NAS Synology DS216j.

Is there a cache option for network sharing or something like that?

Thank you for your help !
