Comment 51 for bug 644644

I can confirm this bug on Toshiba NB205 netbook (full model number: NB205-N311/W) and fresh Ubuntu 10.10 installation with all recommended updates installed (no unofficial/third-party repositories are used).
This computer is a typical Atom N280 based netbook with 945GM chipset and Intel HD sound card with Realtek ALC272 codec.

PA crashes almost everytime when I try to open a video file in Totem. Sometimes it crashes right after the start of video playback, sometimes it plays video for a few seconds but the video output is slow (lags), the CPU usage by PulseAudio process gets very high and after some time PA crashes again. In rare cases video in Totem plays just fine, but after some seeking it could crash again. The error messages are always the same:
pa_stream_cork() failed: Connection terminated
pa_stream_writable_size(): Connection failed

The problem appears only when Totem is used. No problems when playing the same video file with mplayer or playing music with Rhythmbox or Audacious.

I've made a detailed pulseaudio log file just like described on https://wiki.ubuntu.com/PulseAudio/Log, you can find it in the attachment pulseverbose.log.bz2.
I'm also attaching all of the ALSA related information from Apport report, full dmesg, dmidecode, lspci (-vvv) and lsmod output.

Please tell me if you need more information or some help with futher investigation of this problem.
