Title:
Ubuntu's switch to pulseaudio broke accessibility for the blind.
Status in “pulseaudio” package in Ubuntu:
Triaged
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_a11y_nostart
* Use orca with pulseaudio via speech-dispatcher:
http://live.gnome.org/Orca/UbuntuJaunty
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
Description: Ubuntu 9.04
Release: 9.04
$ apt-cache policy pulseaudio
pulseaudio:
Installed: 1:0.9.14-0ubuntu20.2
