Sound Problems

[Patrick Dahiroc <patd@dahiroc.net>]

i've just finished building kernel-2.2.15 and i think i've done
everything to make my sound card work - SoundBlaster PCI 128 CT4700.
below is the output of cat /dev/sndstat 

**------------------
yakko:/home/patd# cat /dev/sndstat 
OSS/Free:3.8s2++-971130
Load type: Driver compiled into kernel
Kernel: Linux yakko 2.2.15 #1 Sun Jun 18 03:02:09 EDT 2000 i586

**------------------

but i still get the message '/dev/dsp: No such device' when i run apps 
that can use sound.

i've looked at the creative lab website to check out the cards
hardware setting:

       Interrupt (IRQ): 5, 7, 9, 10 
       DMA Channel: 0, 1, 3 
       Sound Blaster I/O Address #1: 220, 240 
       Sound Blaster I/O Address #2: 388 
       Base/MIDI port I/O Address: 320, 330, 340, 350 
       Wave Synthesizer I/O Address: 530, E80, F40 Hex 

are the "Card config:" values from above correct with regards the
hardware info?

my sound card is my only PCI device.  dmesg has some bad output
concerning PCI device.

	PCI: PCI BIOS revision 2.10 entry at 0xfb4d0
	PCI: Using configuration type 1
	PCI: Probing PCI hardware
	PCI: 00:3b [1106/3040/000604] has unknown header type 00, ignoring.

could this be the problem?  what does this mean?

but dmesg also tells me:
	Sound initialization started
	Sound initialization complete
which makes me thinks that maybe things are okay.

lastly i read in the kernel sound docs that to make /dev/dsp work i
need to configure the kernel for 'digitized_voice_support'.  however i
did not encounter this option when i did 'make xconfig'.  if i do have 
to turn this option how do i do so.

thanks
