  up to now, pulseaudio always failed, but at last I could start it
  after removing the ~/.config/pulse directory.
  I could then run pavucontrol, kmix, pactl, but still impossible to
  have sound through the speaker, even after:
     ==> pactl set-sink-port 1 analog-output-speaker
     ==> pactl set-sink-port analog-output-speaker
     using the devices given by "aplay -L", I only get the sound
     through the headphone,
     Idem with vlc(output set to pulse)
     with ==>speaker-test -Dpulse -c 2 -t wav    , I get:
      speaker-test 1.1.3

      Playback device is pulse
      Stream parameters are 48000Hz, S16_LE, 2 channels
      WAV file(s)
      ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM pulse
      Playback open error: -2,No such file or directory
