Bug Description
Binary package hint: pulseaudio
The switch to pulseaudio has made screen readers, on which the blind depend, unintelligible.
The recommended workarounds are, in this order:
* aptitude remove pulseaudio
* touch ~/.pulse_
* Use orca with pulseaudio via speech-dispatcher: http://
The problem appears to revolve around pulseaudio's lack of support for mmap, and libportaudio's dependancy on it:
$ LIBASOUND_DEBUG=1 espeak "This is a test."
ALSA ERROR hw_params: set (ACCESS)
value = MMAP_INTERLEAVED : Invalid argument
...
$ lsb_release -rd

Removing pulseaudio will break important stuff (like your sound preferences) in Ubuntu 9.10. See: https:/ /bugs.launchpad .net/ubuntu/ +source/ gnome-media/ +bug/400973
