My three year old promedia has always worked like a charm. Wednesday it worked fine. Last night I turned on the comp for some gaming and I had no sound except some bass rumble and some occasional pops from the speakers. I checked EVERYTHING! The sound card is fine,another set of speakers works fine,I can run headphones fron the control module, the software is fine. If I turn the volume up REALLY HIGH I get some muffled sound from the speakers. WTF??? any ideas, Yes I checked all the connections and physical wiring. Im afraid something has died in the amp portion of the Sub??? Any help is appreciated.
