The device is supposed to be big-endian only. Try plughw:1,0 instead to convert endianness.
Yes, that seems to work! Only for analog output though. When I try with digital I get the same error again.

The plug plugin doesn't handle the automatic conversion of IEC958-subframe formats. You'll likely need to create a PCM configuration to use iec958 plugin properly (better as a card-specific config stored in /usr/share/alsa/cards). Some config files there already use iec958 plugin, such as ATIIXP-SPDMA.conf.
There is already a /usr/share/alsa/cards/EM8300.conf with EM8300.pcm.iec958.0 {...} (http://pastebin.ca/raw/891351) from Ville Skyttä but I don't know how to use it. Neither how to create a PCM configuration for the iec958 plugin. I guess I'll wait for some dxr3 devs to join the party :-)
Thanks for your help.
