Sound Problem - SoundMAX Integrated Digital HD Audio

Hi all

Like the title says, i'm having problems with my front right speaker. It doesn't work..

The sound system worked fine up until I used it on this rig.

**I have Vista Ultimate 64x OEM.

**It is a Creative Gigaworks G550 Wireless.

**I have a ASUS Rampage Formula Motherboard with a SoundFX card that is a SoundMAX Integrated Digital HD Audio drivers.

I have installed the latest drivers, along with uninstalling them then REinstalling them.

I have switched the speaker to the connection of another speaker and its working. So the speaker isn't dead.

I switched the wire that was going to the subwoofer and the front right speaker to another output on the subwoofer and its working. So the wire isn't faulty.

I don't believe the speakers are broken because I have had my motherboard and graphics card quit on me in the past 2 weeks. I am reluctant to believe now my speakers are broken too.

If anyone knows what approach I should take to maybe troubleshoot this, that would be great!
