Hello
I want to play star trek armada recently,and i have the same problem.I know this is an old topic.But i think i solved the problem.I am not an english user(so i hope i dont write stupidity),actually i stole this account,because i dont want to register
So i try everything what you write,this is not a hyperthreading issue.I try to change compatibility mode,but didnot work also.When i trying things,once time it worked,i dont know why because later the probem comes up again.So i tried to reconstruct the parameters ,when it worked,and i wondered.When i opened an internet explorer window,minimized it and run the game it works normally.i tried 4 times again to be sure.i dont know how it possible,but it works.When i close the window it wrong again.I hope it dont depend on other parapeters,but i run it windows nt compatibility mode.
for the soundproblem: run dxdiag from startmenu/run and try to change hardware acceleration opinion.It works on basic acceleration(i dont know in english).
