I can't offer much technical help except:
1. Make sure the sound card is outputting a signal 
    by trying another speaker or headset in the same jack.
2. Use a voltmeter to check for proper power supply to the system.

>Hi There,
>I have lost my sound on my sound system.  It's an Ultra 5.1  Pro Media, put 
>out by Klipsch.  I have sound on  my tower, but the  little box which houses 
>the circuit board is apparently not  working.
>I have taken it apart, but does anyone know which, mostly likely,  of the 
>diodes, resistors and such, it might be before I take it some  where.  I want to 
>try and fix it myself first.  Since the light does  not go on to also tells me 
>there is no sound, but figured this little box is  where all the brains are.  
>Any help would be greatly  appreciate.   Harriet
