I have current version of Nero 6 including VisionExpress (2,1,0,4) and I can't capture audio (nor do I hear it before or during caputing) from my TV card from either the TV tuner or the Audio In (using VCR). I "know" everything is correctly connected and the setting are correct in "Sounds and Audio Devices" in Control Panel, both playing and record. I can capture audio when using WinFast PVR, ULead Movie Factory 2 or VideoStudio 7 and WinDVD Creator or WinDVR.
To try to solve the problem I just did a clean install of Win XP Pro and only loaded the current drivers from Leadtek (didn't instal WinFast PVR software) and Nero . Installed all Windows updates, still couldn't capture sound. Installed Winfast PVR software and ULead MovieFactory 2 and they both capture audio, but Nero doesn't.
My sytem is AMD 1900+, MSI KT3 Ultra, 512MB, 60GB primary HD, 160GB secondary HD (Where captures are stored), Radeon 9600Pro, Live 5.1 sound card.
