Burned out/Damaged my sound card?

[Gazoya]

So I was recently converting audio files in which something went wrong with one of them and produced a horrid screeching sound. Couple minutes later, I realized I can't hear any sound from my headphones or speakers. I plugged my headphones into my MP3 player and it works fine. Both my headphones and speakers connect to the back audio port.

So what went wrong?

Im questioning cause versus effect. Mainly, was the screech caused by the conversion gone awry or was it really because the sound card blew a circuit? It is hard to see how an audio stream on the PCI bus could damage the sound card circuit.

Go thru your OS settings for the sound (top to bottom - begin with the device manager & go thru all available sound control panels). Sound in Windows can be tricky as there can be as many as three competing sound control layers/applications vying for audio level control (eg, the OS, the card's installed control panel, a specific application using the sound).

You were correct C1, during the encoding, Windows muted one of the volume bars that I don't really notice. Oh man I feel pretty dumb, but thank you for pointing that out and resolving my issue for me.
