For about a week now I have had a problem with my 5.1 sound. The subwoofer does not work in Direct3D games.

I notices my sub stopped pumpin in ut2004 the other day. So I thought wtf.

Ran test out of game using AC97speaker test, output was fine for all 6 speakers.
Ran test in Win Media player, output was fine, all 6.
Ran test in DooM3, output was fine in all 6 speakers.
Ran test in FarCry, output failed to come out of subwoofer, only 5 speakers worked.
Ran Test in UT2003, failed to come out of subwoofer, only 5 speakers worked.
Ran Test in UT2004,failed to come out of subwoofer, only 5 speakers worked.

It only fails to work in Direct3D applications. Which Is why I tried all the following fixes.

So here is the steps I have taken to try and fix this:

Updated AND rolled back sound drivers.
Updated AND rolled back ati catalyst drivers.
Uninstalled DirectX AND then reinstalled.
Formatted and reinstalled WinXP AND all applications.
Thrown multiple hissy fits and tussies.

Can anyone help? This is driving me NUTS!

If not, any suggestions where the best help would be?

Cheers. Wakk.

This is not my scene at all but....
Seems like your speakers and everything external to the PC is ok as tests give outputs.
Have the games which are now causing trouble worked ok in the past? Ie. are the games at fault?

Have you checked the game's audio setup to see if they are still right? Seems you should have tried a simple System Restore and if that didn't help then re-install the games.

EDIT: No its still stuffed the same as before.
