[linux-audio-user] Rip sound from a VCD

Dear all, I was trying to rip some sound from a VCD today. I was hoping to play it in one ALSA application (Kaffeine) and simultaneously record in another (Rosegarden or Rezound). But when I tried to launch the recording application, it said it had no access to the audio. I also tried launching Rezound, then Kaffeine. This time, Kaffeine said it couldn't access the PCM, and it played without audio. Does this mean applications can't share the sound under ALSA? Or am I missing something? I'm running Gentoo with 2.6.16 kernel, ALSA 1.0.10 (I think - not quite sure how to check this). Any hints welcome. Peter C
