Ouch, you do not have to pay any money to get drivers. They are free to download/update.
Are you wanting help to 'get a refund'
or to fix the 'audio output' problem?
Please give more details of the system you have:
XP, Vista...? and the Audio setup - you say it's USB? What equipment do you have?
What happens when you try to play a CD?
We will help if we can.
