Sure it SAYS it has 4 channels, but only two are accessible from JACK. I have one and have used it for years, but I now need more outputs. And, also, the output of the "other" 4 channels is just RCAs. I need 4 channels output, USB1.0, 44.1Khz/24bit. I could use a cheap 5:1 home-theater USB fob type interface, but the sound quality would probably suck, and it sure won't give me balanced outs. > > Does this Unicorn exist? Anyone seen one? The Maya USB 44 comes close to your specs: It has 4 in 4 out, running at 44.1 or 48 kHz with 18 or 19 bits per sample (in and out differ a bit, but both is more then 16 bit). Completely bus powered, works well with ALSA/Jack. See for example http://www.thomann.de/gb/esi_maya_44_usb.htm I don't know the exact specs of the DAC/ADCs, but I can check - they are easy to open. If you like I can send you a picture of the opened device (but not before tomorrow, I don't have one with me right now). -- Giso > > -ken > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user@xxxxxxxxxxxxxxxxxxxx > http://lists.linuxaudio.org/listinfo/linux-audio-user _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
