what software do you use to sync to the player? i think there's a way to tweak volume in windows media player when syncing to an mp3 player.

 

the player doesnt sync right the firmwares trying to go but i cant find new copy just my luck....

and iv used audacity befor and didnt care for it

 

there's one other audio editor i use, and prefer over the others.

Hi, you don't mention here what you use for listening music. i.e. Your speaker system. I'm using SRS Audio sandbox. Its really working good and can amplify audio output as double. You just try it and you can contact me for further help. You are always welcome. Here its homepage http://www.srslabs.com
