[orca-list] For those wishing to install Ubuntu 9.04 alpha 3

Hi Everyone
For those wishing to install Ubuntu 9.04 alpha 3, I've encountered the  
following problem and workaround. This, for me, was preventing the  
boot-up accessibility option from working.
Problem: Portaudio, on which espeak depends, is compiled to use OSS by  
default and, via padsp, is wrapped to using Pulseaudio. However, the  
snd-pcm-oss and snd-mixer-oss modules required for oss output are not  
loaded, rendering espeak unable to speak. I'm unsure if this happens  
on all systems, but I've verified it on mine, and this issue is still  
present as of the most recent lived build. While padsp does wrap  
espeak to use pulse, it needs to be able to communicate with the oss  
device for it to do so, hense these modules need to be loaded.
Solution: Once the livecd is booted up (note, these alpha builds do  
not seem to play a login sound) open gnome-terminal (alt+f2 followed  
by gnome-terminal). Issue the following command:
sudo modprobe snd-mixer-oss snd-pcm-oss
Now, to test, issue the command:
espeak hello
Espeak should say hello. Now, run orca and go through the setup. When  
it asks you to log out, say no as this isn't working properly on the  
livecd, at least not for me.
To log out manually, do the following (note: ctrl-alt-backspace is  
disabled so this shortcut won't work anymore to kill the X session):
alt+f1, left arrow, down arrow, l, alt+l.
The disk should spin and you should then get the drum sound,  
indicating that you are at the login prompt. Login with the username  
"ubuntu" without the quotes. press enter twice as this user has no  
password. From here on out, it is exactly like installing Ubuntu 8.10:  
envoke gnome-terminal, sudo su, start orca with --no-setup and run  
ubiquity.
I hope this helps someone out. I'm unsure if all systems encounter  
this issue, but if you do encounter it hopefully this helps you get  
around the bug.




   The major difference between a thing that might go wrong and a  
thing that cannot possibly go wrong is that when a thing that cannot  
possibly go wrong goes wrong it usually turns out to be impossible to  
get at or repair.
