X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=b64259b2950d6bf0e6572e3362b6ee109104192e;p=flightgear.git

allow disabling sound completely (note: openal gets initialized but shuts down a bit later leaving the soundmanager to handle only very specific commands). At this time by specifying '--prop:/sim/sound/enabled=false', not sure why '--disable-sound' doesn't work properly
