I bought a ESI-Juli@ card ( http://www.esi-audio.com/products/julia/ ) specifically to record 24bits/192Khz and it was Linux compatible. It records at 192KHz just fine, but only 16-bits. When I get in the Jack Setup the "Word length" is set to 16 and is grayed out and cannot be changed.

I also booted it with AV Linux and does the same thing. The 16 word length is grayed out in the Jack setup.

Is there something somewhere I need to configure or is it because ALSA cannot use the 24-bit capability of the ESI-Julia card?
