Title:
  audio unreliable with eglibc 2.15

Status in “eglibc” package in Ubuntu:
  Confirmed
Status in “eglibc” source package in Precise:
  Confirmed

Bug description:
  Audio is completely unreliable after upgrade to eglibc 2.15.

  - Google+ hangouts, which use the google-talkplugin package from http://dl.google.com/linux/talkplugin/deb/, initially have audio working, but within a minute or so the audio cuts out (in both directions).  This plugin uses pulseaudio via dlopen() of libpulse.so.0.
  - Skype, from the oneiric partner archive, exhibits similar behavior: audio is bidirectional when the call is established, then after a minute or so the input cuts out (despite pulseaudio's volume meter showing that audio is still being picked up from the mic)
  - Quodlibet (pulse-enabled media app implemented in python) plays music fine until it suddenly stops after a random period of time.  In my latest test, the current track has stopped at 4:59 into the song.  The UI still responds fine and if I select a different song to play, playback resumes.

  The G+ regression has been reported by several other people on IRC.
