Computer: p6140f Prod# NP192AA
Problem: I am seeing an offset voltage on the line input of about 200 mV when recording. I see it using Audacity, Goldwave, Adobe Soundbooth CS5 or the Windows recorder. OS is Windows 7 Ultimate. This offset reduces the dynamic range available. Goldwave can remove it after the fact. The computer was purchased with Win ME installed and did not exhibit the problem then. After a hard drive crash, a new C: drive was loaded with Win 7 Ultimate (32 bit) and the offset showed up. I assume this is a driver or OS problem. I have not found an updated sound card driver for this machine. Any suggestions would be greatly appreciated.
