[Bug 929713] [NEW] audio unreliable with eglibc 2.15

[Steve Langasek]

Public bug reported:

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.
