I am also having this problem and not sure what is causing it. I play both FFXI and FFXIV and can log in and play FFXIV fine but when I try and log into FFXI it times out after the character selection. When I go back to the game menu to try to log in again I find that there is no sound. Is this problem related to the updates? If not I find it strange that I can play one SE game and not another atm. No settings have been changed on the pc or router.
