Bug#693274: pulseaudio: audio playback too fast and only silence

[David Kuehling]

Package: pulseaudio
Version: 2.0-6
Severity: normal

Hi,

after upgrading to wheezy, audio playback worked normally for a few
days, but now failed beginning on nov 14.  I updated packages regularly
and I'd suspect a newer version of pulseaudio triggered the error, as I
didn't touch any of the audio-related stuff.

The symptoms: Applications won't complain when playing back audio.  They
just run the playback too quickly (approx 5.75 times as fast as
real-time) and no audible audio is actually output on the speakers
(complete silence, no noise etc.).

This happens consistently when playing via alsa, directly via pulseaudio
or via libSDL.  I can still play back audio when using the OSS API.

Illustrating the issue with command 'play' from package 'sox':

  $ time play  01_So_What_-_Ast0r.flac  -t alsa

  01_So_What_-_Ast0r.flac:

   File Size: 67.5M     Bit Rate: 956k
    Encoding: FLAC          Info: http://kindofbloop.com/
    Channels: 2 @ 16-bit   Track: 1
  Samplerate: 44100Hz      Album: Kind of Bloop
  Replaygain: off         Artist: Ast0r
    Duration: 00:09:24.84  Title: So What

  In:100%  00:09:24.84 [00:00:00.00] Out:24.9M [      |      ]        Clip:0    
  Done.

  real	1m38.126s
  user	0m8.261s
  sys	0m2.684s

I.e. it "Plays back" a 9 minutes 24 audio file in 1 minutes 38.  Exact
same behaviour when playing back with option "-t pulseaudio".  Playback
works when playing with "-t oss" or "-t ossdsp".

Same problem when using mplayer for movie playback.  Movies play back
much too quickly (mplayer uses the audio playback for timing the
frames), when playing via "-ao pulse", "-ao alsa" or "-ao sdl".  Only
"-ao oss" works.

I have merely these pulseaudio-related messages in my syslog:
