posiadam 2 karty dźwiękowe. Pierwsza z nich to CMedia CM8738, która jest moją kartą główną. Druga to ATI HD Audio. Korzystam z OSS4 + pulseaudio. Moim celem jest doprowadzenie do sytuacji, w której pierwsza karta będzie obsługiwała wszelaki dźwięk w moim systemie, a druga tylko do skype. Na razie doprowadziłem do stanu, gdzie dźwięk z pierwszej karty uzyskuje na dsp, a z drugiej na dsp2. W tym momencie utknąłem. Pomyślałem sobie żeby skopiować dźwięk z pierwszej karty na drugą. Tylko nie wiem jak tego dokonać.

OK problem rozwiązany.
Uruchomiłem obie karty dźwiękowe. Tak jak zakładałem... CMedia obsługuje "wszystko", a zintegrowana tylko do Skype. Problem polegał na tym, że nie udało mi się wyprowadzić dźwięku w skype na inne wyjście niż "defalout". Dlatego zrezygnowałem z tego protokołu i spróbowałem Jitsi, w którym mam dowolność wyboru wyjść na obie karty.
