Same issue here. Weird thing is, it worked flawlessly the first day, but
it's been skipping frequently since the second one.

Title:
  a2dp skips terribly

Status in PulseAudio sound server:
  New
Status in “bluez” package in Ubuntu:
  Confirmed
Status in “pulseaudio” package in Ubuntu:
  Confirmed

Bug description:
  As I upgraded to the Karmic alpha, bluetooth audio (via a2dp) stopped
  working properly. It was working fine in Jaunty.

  My headphones are detected and configured by pulse, but the audio
  skips as if it's spending half of each second paused. Music is
  buffered so that after I click stop on rhythmbox (or whatever--it
  happens with whatever player I use) the audio continues until it's
  caught up.

  syslog is full of the following lines:

  pulseaudio                    1:0.9.15-4ubuntu2 0

  pulseaudio version 1:0.9.16~test2-0ubuntu1~ppa3 from ubuntu-audio-dev
  didn't help.
