wine-1.3.25 audio reversion bug.

The major update to wine-1.3.25's sound drivers reverts to an old wine 1.1x and 1.2x bug wherein sound in Tribes (1.3 and 1.4) will stop after a minute or so of play. Going into the menu system restores sound, but only for as long as your are in the menus. Game sound does not return until Tribes is closed and reopened.
