I don't remember what I read exactly (and google didn't help) and which card exactly it applied to. I have soundblaster live! platinum (with live drive). What software do you use?

Line LiveDrive, Line LiveDrive Capture, Line2 LiveDrive 1, Line2 LiveDrive Capture 1 are all the way up, guitar pod (line6) is connected to two rca connectors on the live drive. However I was recording mono only (in audacity) so I guess only one of them was recorded. when recording only (no playback at the same time) the recording is OK, when I play click track at the same time the recording is very bad. I was recording at 44kHz, thought that might be a problem so I switched to 48kHz but then there's no full-duplex at all (i.e. the already recorded stuff does not play when I record). is this a problem of my setup or audacity? (I can't get muse working, it hangs whenever (trace reveals it's reading from some pipe) I try to save (which is required to create audio track)). Any other simple recording programs (that would make it possible to play the previously recorded audio (aka full-duplex aka overdubbing)? erik
