I am not quiet able to understand what I had did here. The system was working well. But some there was a error related to Active mixture device. I checked in Device Manager and there is no errors at all. I went into the bios also about the sound chip. It looks to be working. But somehow there is no audio at all. I checked on msconfig also and found that the audio driver is configured to load on startup. I am having a sound card on my system. I am not using the onboard audio. Is that is what is the cause of issue. How can I set the sound card as my default option to listen audio.
