Audio starts after video

[snoopyx]

Hi Guys,

I'm using a A110 for a couple of weeks, was reading the forum from the day I bought it to prepare for the big day the poppy arrives. It's my first NMT and I got it used. Plugged in a new 2TB green HDD and let the Poppy format the disk and install the apps. It looks and works great but for one little thing. When watching a video, only tried mkv for now, the Audio track starts a couple of second late. It's not much but just enough to miss the first two sentences on a show. The audio track is not asynchron it's as somebody forgot to undo mute on the TV.
Sorry if this issue was already discussed. I searched but didn't found anything, maybe used the wrong keywords, dunno.

Nobody has an idea?

are you using optical audio?

No, audio is via HDMI, and for now reproduced by the TVs speaker (Toshiba 40XV733G).
