i found a solution from terminal with command

vlc --aout alsa --alsa-audio-device default

.how i can that the sound is stereo that both internal speakers are working?

What do you mean with poor quality? Artefacts in signal? Does speaker-test work with internal speakers? To check stereo run:

speaker-test -c 2 -t wav

If you are running pulseaudio, you may want to check this thread and this wiki article.
