Try typing

Code:

killall esd

into the terminal before playing.

Can type

Code:

esd

after playing.

that would work but i dont think you should have to do that ubuntu should really fix that

Meh it's not a big deal, you can just make a shell script to do it for you.

**CameronCalver** · July 17th, 2006

The solution to this problem is to create a files called .openalrc - that is DOT+openalrc (which becomes a hidden file as are all configuration files in your home directory). Then enter the following text into the file:
define devices '(pulse))

NOTE: there is no closing ' character - do not put one in.
This will direct FlightGear's sound system to use the esd sound server as it's output device.

This file can be created in one shell command:

$echo "define devices '(esd))" > ~/.openalrc

NOTE: The tilde character ~ in the above command is shorthand for your home directory.

If you have the pulseaudio sound server installed then it gets complicated, unfortunately. I have found that only by killing the pulseaudio sound server will FlightGear sound work.

Happy flying!
