However, I see no viable replacement for Envy24 cards on PCI-E.Oxygen and X-Fi just don't cut it. Anything else? Of course, when it comes to Envy on PCI-E there is Tokyo Style S010DCS-SEV24, however that card doesn't support ASIO and since it usesPCI <--> PCI-E bridge it's performance (in low latency operation) willprobably suck. And also it's not aimed at producers, and it doesn'teven support ASIO in Windows. I believe there are no MIDI portseither. Therefore, out of all those "new" Envy24-based cards (since that'sbasically what's available in this price range), Quartet stands out asbasically the best producer-oriented solution out there. Even morethan that - this is by far the best Envy24 card I have seen so far.Almost like there is nothing to add :-) It's not available where Ilive (Croatia), but it might be in the future since Auzen started todistribute it, that's why I was interested in possibility of ALSAdriver for it appearing. Well, I will contact Infrasonic in the coming days and let you knowhow it went. Fingers crossed. -- Vedran Miletić_______________________________________________Alsa-devel mailing listAlsa-devel@xxxxxxxxxxxxxxxxxxxx://mailman.alsa-project.org/mailman/listinfo/alsa-devel
