First of all I've tried google and different set ups in mplayer.

Mplayer/kmplayer and zoutube lacks sound

That's what i've found in logs:

Also, would be nice to get it working faster, so i dont have lag when I plug it to a TV.
The sound is working normally in the 'default' player. Thou also lags.
