You should have 96000Hz and 32 bit for the Delta 44 if you
use OSS. With ALSA I do not know. There have been problems
with ALSA in the past.

The reason OSS does not work is probably that you did
not run configure, then make after you installed OSS.
I suggest the following sequence:

1) ./clean
2) ./configure
3) make

Then use ossmix to set envy24.rate to 96000
Do this sequence every time you replace the sound system.
configure will tell Linrad where to find the OSS files.
You have probably compiled linrad with the ALSA include 
files, then you execute with the OSS device files. That
would explain why you do not see 32 bit.

I think it is even possible to run ALSA for one soundcard and OSS
for another - but I do not know any details.
