Pulseaudio interrupts startup noise

sound info

What is the spew in ~/.xsession-errors regarding pulseaudio?

I've attached .xsession-errors . Looking at it, this may be it?

I reporta similar bug today: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/253671

But the diference is that pulseaudio breaks. Log:

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

This bug was fixed in the package pulseaudio - 0.9.14-0ubuntu11

---------------
pulseaudio (0.9.14-0ubuntu11) jaunty; urgency=low

  [ Daniel T Chen ]
  * Reenable 0030_set_tsched0.patch, which re-disables glitch-free;
    too many users are reporting regressions and audio aberrations.
  * Adjust 0003_change_resample_and_buffering.patch to use linear
    resampler to work better with lack of PREEMPT in jaunty's
    -generic kernel config (LP: #207135, #322250, #332761, #335955,
    LP: #336965).
  * Last upload, specifically 0091_workaround_alsa_horkage, fixes:
    LP: #235990, #237443, #279847, #317997, #323185, #330814,
    LP: #334874.
  * sudo -H change in ubuntu6 fixed LP: #312505.
  * Closing old bugs fixed in 0.9.11+: LP: #187963, #193520, #211052.
  * Refresh 0006_regen-autotools.patch.
  * Add 0043_load_sample_dir_lazy.patch to cache
    /usr/share/sounds/ubuntu/stereo/* in default.pa.
  * debian/:
    - control: Build against libcap2-dev (LP: #339448);
    - copyright: Update copyright from Debian's 0.9.14-2;
    - rules: Add DEB_OPT_FLAG = -O3 as per recommendation from
      pulseaudio-discuss/2007-December/001017.html.
  * Refresh fixes from git HEAD:
    - 0038_handle_errno_properly.patch,
    - 0091_workaround_alsa_horkage.patch,
    - 0092_fix_null_pointer_access.patch.

  [ Luke Yelavich ]
  * Add a special case to prevent Pulseaudio from being started when the
    blindness accessibility profile has been enabled from the Ubuntu live CD,
    and for an accessibility install. Unfortunately Pulseaudio and speech do
    not currently work very well with each other, and its too late in
    the cycle to solve this problem any other way.
