Actually it is playback (and thus duplex) that I'm having trouble with (alsa-driver-0.9.8 and jackd-0.80.0). Capture works fine from hw:0,2 using jack via my .asoundrc.  It's when I try and tell jack to play (both -P and -D options) to hw:0,2 that my ad/da converter gets blasted into this weird loop (a midiman flying cow), like I described in my earlier post.  If the whole thing is caused by the discrepancy in the bit sizes in newer versions of alsa-driver, i'm fine using 0.9.2 until that's resolved (i'm very happy to test when it is, btw), since that version works perfectly for full duplex spdif operation.  For posterity I posted a bug to alsa's sourceforge site:

thanks again,
