Yes I think I have the same problem with a Soundblaster 16 card. I compiled
sound in the kernel (no module) and while booting I get the message
"cannot allocate DMA buffer". System has an Adaptec 2940 controller. For
reference I include the output of /dev/sndstat:

and the relevant output of dmesg:

I think it is no conflict with my SCSI controller as suggested in the docs?!

Any help would be great
