[LAU] Sharing sound card

Haven't been using Linux for sound recording for some 5 years now, so I feel rather out-of-date. I used to use jackd, rosegarden, timemachine, etc, but I left the music behind and now into ham radio. I have a fresh Kubuntu install (10.4) and I want to run Fldigi (which reads line-in and does PCM out) and simultaneously record everything that is being read-in and transmitted out. Fldigi is no jack application and I can't find a workaround to make it like jack. I also can't find out how to directly talk to my sound card (Ensoniq ENS1371). It must be possible to share and route all the audio in my box, or not? Anyone care to guide me back in and give me some pointers on where to start? Greatly appreciated. Hans (ham call PA2BX)
