So I turned on my RFM today, and to my dismay I have no sound! Ran the test report and it is complaining about the DSP no clearing or resetting, I forget the exact words. What's my direction.
 
If everything works then I'd suspect the PRISM card which those cards are infamous for being crap and is why NUCORE was invented. Not much help there for you.

You could have a bad U109 on thsi PRISM card. Or it's possible if the previous owner either swapped in the SWE1 pf and the chips. Or the firmware on the board needs to be flashed back to RFM.

When you go into the service mode do you get any errors? When you turn it on do you see a DCS error?

That's not true... the Prism cards are pretty damn reliable (you rarely hear of one going bad). It is the MediaGX motherboards that are the problem (many of which have succumb to the "capacitor plague").
 
Here are the 2 sound related errors it is giving me (everything else are switches I need to replace)

DCS: DSP failed to reset
DCS: SRAM Test Failed
 
The Pin 2k's have a sound card inside the computer box mounted to the side. They do not use the on-board sound on the computer board. Sounds like the sound card may be bad. It might just not be plugged in, as it also requires power...

Also looks like you have bad ram.

You can pull the prism card and hook the computer up to a regular VGA monitor and plug in a IDE cdrom drive, AT Keyboard then load up a ram test, etc...

The on-board sound card that you refer to is only an audio amp and it gets all the sounds from the PRISM card. The bad ram issue, I believe is connected to why the DSP failed to reset. I have narrowed it down to the PRISM card, but was curious if you guys know what component issue I may be looking at.
