Mac Sounds problems

Hello,

Do anyone knows if there is some kind of problem with T2D running in Macs (sound related) ?
I was using the old version of Torque, and just recently found out that it has no sound in Macs..,
Ok, so i tought the problem was with the old release of torque, but i just installed the most rencent release
and the torque demos have no sound either..,
What's wrong with it ?

Can anyone help ? I'm getting out of ideias here..,

thanks,
Bruno
