My bet, pulse and alsa are fighting, which is usually the case. Alsa is a direct link into your sound card and will accept mathematical wave functions as input and output sound. Pulseaudio or Jackd is a digital mixer, so it takes all the applications that wants sound, mixes them together, and then sends the final waveform up the chain.
