Well I have just got a new computer of Dell for my home and have just installed the operating system of the Windows 7 in the computer that I am just making use of and also the system that I have just installed is of newer versions. I have just started to make use of the Realtek HD Audio Manger, for the managing of the audio files that are being used by me in the system. But I just started for making changes in it but I don’t know what kind of the error just appeared to it, the front input and output files are not working and I have no idea why this issue is being faced by me. I have just tried out many solution but all were not at all useful. Please help me out with this issue and tell me what the basic problem with it is.
