[Bug 644644] Re: Frequent PA crashes during playback - pa_stream_cork() failed: Connection terminated and pa_stream_writable_size(): Connection failed

[e_james]

EeePC 901, Ubuntu 10.10

I'm a newcomer to linux and there is much I don't understand but I do
have some computer skills and I have noticed that no-one has mentioned
audio sampling rate. When I discovered this problem and looked for a
solution I found that some video files will play properly and some
won't. So I did some experiments with the following results.

Any file where the audio is mp3 or aac or ac3 with a sampling rate of
22.05 kHz will play in Totem without problems.

Any file where the audio is mp3 or aac or ac3 with a sampling rate of 24
kHz will fail to play in Totem with the error messages described above.

Since 44.1 kHz or 22.05 kHz seems to be the accepted standard in North
America, I suspect that someone wrote a piece of code which, in effect,
assumes that the sampling rate can only be 44.1 kHz or 22.05 kHz. Many
years ago I made a similar mistake and trashed an operating system.

Unfortunately for me, the majority of my video files use mp3 at 24 kHz
because I have found that 22.05 kHz doesn't sync properly with the
video. I believe that it's something to do with the PAL TV standard in
Europe.

Bug description:
  Binary package hint: pulseaudio

  With the recent kernel and pa upgrades in Maverick I am seeing very
  frequent crashes in Totem trying to play back audio as well as video.

  The error messages in question always arrive together and are as follows:
  pa_stream_cork() failed: Connection terminated
  pa_stream_writable_size(): Connection failed

  The machine in question is an Asus EeePC 1002HA and the problem
  persists on both the USB attached speakers and the builtin HDA device.
