Great Alternative to the sound card

Having a laptop for three years who has traveled extensively and worked, I was not too surprised that the sound card falls in the roads ... But I wanted to wait for the release of windows seven before buying a new one. This key was a good alternative and I started despite my doubts about the quality of sound. No regrets! The sound is impeccable and for a very correct one even has a microphone input prices which I have not yet needed. The installation is automatic and I could enjoy again very rapidemment sound. A very satisfactory product that I recommend.
