[alsa-devel] ALSA Problem - Broken Pipe

Hi all,
I apologize if this isn't the right place to ask for help, but no one who
I've asked knows how to help and I'm somewhat new to Linux.
I'm running Ubuntu Hardy Heron and haven't changed any config files
(practically a fresh install) however ALSA does not work properly and I
assume that because of this, Pulseaudio doesn't work either (it breaks when
ALSA does). Playing a song, I can hear the song for a random length of time
and then it cuts out. If I run VLC from a terminal, it claims "alsa output
error: write error (broken pipe)" as the cause and continues to write that
over the screen until I force VLC to quit. If I restart the song again, the
same thing occurs. Pulseaudio cuts out and says it gets a POLLERR from ALSA.
When I login, only part of the login sounds play and are cut just the same
as any songs or audio files I try. It seems like my sound card is detected
fine, and OSS works when I select to use it instead. It's on a laptop, a
Toshiba Satellite a70.
Below I've listed the alsa-info.txt as per
https://wiki.ubuntu.com/DebuggingSoundProblems.
Thanks,
Kristin
