Hi! I have Altec Lansing ATP3 speakers (two satellites and a subwoofer) and a Sound Blaster Live! Platinum sound card. Lately, I have noticed a slight crackling noise sometimes when gaming, or when I hear sound (near the end of whatever sound I hear) and I don't know if my speakers are blown or my sound card is fried. The only reason I question it is because I have the crackling sometimes too in my headphones, which are not blown. Is there a way to test out to see if they're blown or to listen real closely or?? Help!
