Daniel: I tried your suggestion (add position_fix=1 to the options snd- hda-intel line in /etc/modprobe.d/alsa-base.conf). If anything, it makes it worse.
I posted this problem to Ubuntu forums earlier today and one other user reported the same problem. I can make do with the applications that I need by just removing pulseaudio but would sure like to solve the problem. Am willing to do some testing if you can think of anything else. ** Summary changed: - Toshiba NB30500F pulsesduio problem + Toshiba NB30500F pulseaudio problem ** Description changed: Binary package hint: pulseaudio Toshiba NB305007 netbook. Ubuntu 10.04 LTS - lucid. 2.6.32.21-generic, running ubuntu-netbook-remix. Problem with pulseaudio (1:0.9.22~0.9.21 +stable-queue-32-g8478-0ubuntu14) . Boot machine and open a gnome- terminal window. At the CLI, hit backspace. You will hear the normal ping/bong. Hit the backspace key a few more times and the sound suddenly changes to a scratchy peep, or may disappear altogether. If I wait 10 seconds the sound returns to normal but repeatedly hitting the key causes the same effect. If I play a song using Rhythmbox the sound goes crappy after a few minutes. Or I can purposefully make it go bad by hitting the backspace key a few times in the gnome terminal window. I have tried all of the common remedies of adding asus-mode4 to the end of the options snd-hda-intel line in /etc/modprobe.d/alsa-base.conf. I tried many different combinations of default-fragments and default- fragments-size-msec in /etc/pulse/daemon.conf, all to no avail. If I purge pulseaudio (apt-get purge pulseaudio) and reboot, the sound is fine although some other sound things do not work as expected (no volume control). But rhythmbox, sound recorder and twinkle all work. NOTE: Purging pulseaudio removes ubuntu-desktop, ubuntu-netbook and ubuntu-netbook remix. But rebooting brings the machine up just fine. If I reinstall pulseaduio, the problems come back... leading me to believe that the problem is with pulseaudio. Any help or ideas would be much appreciated.
