The RealTek HD audio was the only Intel HD codec/chips that had issues with WinXP because the Intel HD driver appeared as separate input and output devices. I have since modified the VIC code to add Realtek HD support and the RAT that ships with AG 3.1 includes it. There must be at least a 100 different chips supported by the ALSA Intel HD drivers. With some of the chips, you need to be running the later ALSA driver and occasionaly there are bugs. Does the ALSA audio input on your PC work with any application? Try 'alasmixer -V all' and ensure you've enabled/selected the correct input. As with Intel's AC'97, enable force AC'97 in the AG Audio Service. Also try switching between OSS and Alsa in RAT. Doug
