Hi, For now Audigy 2 ZS is suported in alsa and works as Audigy 1. In CVS is support for side speakers. Maximum sample rate is 16 bit / 48000 kHz for now. There is some progress and in near future 24 bit / 96 Khz playback will be supported too. Look at http://sourceforge.net/mailarchive/forum.php?thread_id=5029036&forum_id… If you need 24bit /96 KHz recording, then soundcards based on envy24 (ice) are better choose for now.
