have you tried the "-c 1" flag for hdparm to enable 32bit-I/O-support ?

this should definitely rock !
note, that i do not remember having problems with a rme-9652 and
kernel-2.4.3 (or something),
although i had to compile the kernel myself then.
i am sure, that i could play-bac 2 files at least.

which soundfile-player do you use ?
under linux i definitely suggest using miller's "readsf" instead of
zexy's "sfplay~" !!
could this be the problem ?
