Thanks guys. I end up buying a SoundBlaster MP3+ USD audio interface. this cost me $40. This device comes with the RCA input and output jacks which I can use to directly connect to my amplify and also comes with mic jack that I can plug my mic in. I think this will work for home entertainment purpose. I have not actually hook up to my stereo system yet. Will let you know what the outcome is. I know buying a mixer will definitely solve my problem but I am not sure if I am ready to spend $300 yet. Maybe later when I have more cash to spend I will upgrade.
