Soundblaster AWE64 question

[Hines, Jim]

Hello,
I have a SB-AWE64 with registered OSS with mixer and AWE options. The card
supports both 8 and 16 bit recording. However, whenever I do issue a 
cat /proc/dma
I get this return.

 1: SoundBlaster8
 4: cascade
 5: SoundBlaster16
 7: aha1542

What is dma 1 used for and why is it set for Soundblaster8 as opposed to 16? I
would naturally assume that  dma 1 is input while dma 5 is the output. Correct?
Someone please explain this to me.

Thanks,
Jim Hines
