This means you are not playing directly to the 2496 but you are
playing to a virtual device called plughw which is then sending the
data on to the 2496.

(I am assuming here that the 2495 is the only sound device in your machine?)

I have no problem playing this file. Note that I did have to use
alsamixer and turn up both of the DAC outputs and make sure it was
sending audio. Like most Alsa devices it's muted by default.

I wondered if it was a 16-bit/24-bit issue but I can play 24-bit files also:

Note: This machine is Gentoo not PlanetCCMRA. Maybe it's a CCRMA
thing? Not at all sure.
