Re: [orca-list] sound on feisty

[Willie Walker <William Walker Sun COM>]

Hi All:

I'm not quite sure about this, but we might be able to hack around audio
device contention in some way using the ESD tools.  Here's what I'm
thinking:

1) Get the esddsp utility.  The esddsp utility fools non-ESD
applications into being ESD applications:

sudo apt-get install esound-clients

2) Modify your gnome-speech Bonobo activation files to include esddsp
before the actual gnome-speech driver.  For example, change line 3 from:

type="exe" location="/usr/bin/espeak-synthesis-driver">

to:

type="exe" location="esddsp /usr/bin/espeak-synthesis-driver">

3) Via the "Sounds" tab on System->Preferences->Sound, check the "Enable
software sound mixing (ESD)" checkbox. 

4) Logout/Reboot.

It's a shot in the dark, but if GNOME is supposed to be ESD friendly,
then maybe we can make things friendly to ESD via esddsp.
