When you first use I was also pleasantly surprised by the sound forth. However, after I wanted to separate the sound card, a lot of the thing first completely apart. Say, I had the upper and lower black part in the hand.
In next times will then try briefly distorted sound. After restarting the laptop, however, was resolved again.
Equal to get a response from the customer, we take care of by my concern. DC a few days later I had a letter from CSL. With a new sound card. I was really totally surprised. And with this sound card I am completely satisfied, because I need it for TeamSpeak. I had at the first sound card probably unlucky and got a defective part caught. But can indeed times happen;) The Erstatz came so quickly (and even without request) and served its purpose to my complete satisfaction =)
