Hello! Ok. This is the deal. I was in playing music (mp3) on my Widows Xp pro computer when I decided to Unzip a Self-Extracting file. So while the song was playing I did so and guess what happened? The wors "Hiss" noise I've heard came up and only stoped when Decompression was done. With the intent of troubleshooting, I once again try to Unzip the SFX file but this time with NO music playing and the "Hiss" noise was gone. Can anyone tell me what happened? Thank you all in advance.
