Xine has video but no sound

Binary package hint: xine-ui

Ubuntu 11.04 64 bit desktop edition running unity.
When playing back video xine has no sound, but video okay. Also, when using Me-Tv, which seems to uses xine for sound, again video okay but no sound. Alsa volume sees xine as using sound, and volume is adjusted to full, but still no sound.
