perfect world sound loss

[flyfisherman]

archlinux alsa sound eveything updated to current releases. been playing perfect world for about 7 months now. the game plays great. the only issue i have is after 6 hours of play the sound stops. music effects everything. i have to log out of game and come back in then have 6 hours till it happens again.exactly 6 hours almost to the second. i have a friend who has the same problem. it's only a minor problem i can live with but was wondering if anybody else has this issue and has a fix for it? can't find anythiing in the logs that seems relevant.
