In addition to the bug as far as restarting the game is concerned, when playing as the Space marines or the Eldar factions, many sounds such as alerts are not played in skirmish mode or multiplayer. Sounds are used properly upon restarting the game however. (I mean restarting the map, of course).
For some reason, the Chaos Marines sounds work just fine.
Never mind, that was for Dawn of War original, Dark Crusade works just fine apart from the restarting the game bug.
