I cannot record on Sony sound Forge Audio Studio 9.0. I chose windows Classi Wave Drivers, under Default Playback Device, I chose Speakers Realteck Audio, under Default Recording Device, I chose Microphone REalteck (Audio) but I still cannot record, Help!
Are you trying to record from the PC's microphone or record what you hear from the PCs speakers? (audio playback from a website for instance),
SF Audio Studio 9 was an odd build and was primarily included with some of Sony's turntables, I had the pro version of Sound Forge 9 which I tried on a Win 10 PC and it worked normally.
