Re: [orca-list] Pulseaudio and speech-dispatcher/gnome-speech in Ubuntu.

Hi Luke.

I don't understand how this setup works.

speech-dispatcher starts at system start up. It uses the ALSA espeak
driver, which in turn blocks the audio device.
Then pulseaudio starts at session start up, and fails to initialize
audio devices because speech dispatcher is sitting on top of that
device.

I don't know why I am the only one experiencing this.

I highlighted this in a launchpad bug:

Cheers,
        Eitan.
