Sun Ultra 20 148 Model : No sound , audio Port Problem

Hello there,

There is a problem with Sun Ultra 20 (Model 148). Here is the problem details,

Operating system : Windows Xp, Linux ( Red Hat )& solaris 10 Multiboot.

After installing Os, & audio driver , I have attached speakers In front panel as well as Back Panel Audio Port. But in my operating system, audio shows everything is ok. its playing when I am playing Music. But there is no sound in speaker. I think there is a problem with audio port jack inside. So please let me know How I can fix it.?

Thanks

Partha
