I am hearing a pretty distinct glitch in the audio about once per second ...
it's not so much of a hard break, but disruption in continuity. I'm not
sure if this is related to a pause in FlightGear, or the openal drivers on
Fedora 9, or what? The once per second audio glitch seems to be more
distinct on lower performance CPU's. (Referring to our cvs development
version of course.)
Regards,
Curt.
