Thank you, Alexander! :)

In fact, this netbook works very fine with audio/oss from ports.
My only problem with audio/oss is that whenever I skip (seek) in a
video or an audio file, freebsd crashes and reboots.

I know it's a problem with mplayer + oss, because, mplayer
with snd_hda works (except speaker) and oss + vlc works

But I like mplayer more than vlc ;)
