[linux-audio-user] Could my system be harmed by "pop"

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Folks, No, I don;t mean pop music..I already know that's harmful. I'm an audiophile (how many of you are?) and I am a linux geek as well. In trying to bridge my two loves, I have hooked my sound card directly to my amp (a Carver TFM-75x) which puts out about 380 watts per channel into 8 ohms. When i restart my system i get a loud thump from my speakers. I have Definitive Technology speakers with built in active subs. I think the thump is coming from both my subs and my mid range drivers. Could this be harmful to my system? What is happening? It is a sound card grounding issue? Can i fix it? Currently i am just shutting off my amp b4 turning off my computer, but there may be times when it restarts itself and I cannot shut down my amp. I'm using a Sound Blaster Live for what it's worth. Thanks, Bearcat M. Sandor
