I have been having an issue where Microsoft Expression Encoder will only show inputs as valid forms of audio recording. This basically means that if I were to be recording gameplay, I could only record sound from a mic, but not sound from the game itself. The only three options for audio recording are "Realtek HD Audio Input," "Realtek HD Digital Input," and "Modem #0 Line Record." My computer is a Windows XP Media Center Edition SP3 (2002) with an AMD Athlon II X4 620 Processor and 3.25 GB of ram. Please help me, as this program is brilliant and has all my wants fulfilled, save this one pesky issue! Any attempts to assist me are gladly appreciated.
