## Setting up a PnP Soundcard
## Anonymous

Make sure that your soundcard is plug and play before you try any of the following.

	Make sure your bios is set to off for plug and play.
	Make sure you know the irq and dma for your soundcard.

You need kernel support for sound to work under FreeBSD. I am assuming you know how to compile new kernel. If you don't, please see the appropriate sections of the .

PnP SoundBlaster vibra16x

You'll most likely end up using pcm0 instead of snd0 since snd0 doesn't allow dma less than 5. Unfortunately, by using pcm0 you won't have support for midi.

Put the following lines in your kernel configuration:

	controller pnp0
	device pcm0 at isa ? port? tty irq 5 drq 1 flags 0x15

Don't add any snd0 devices! (It will give you error if you try!)

After preparing your kernel configuration, perform the following:

  1. Compile new kernel
  2. Install new kernel
  3. cd /dev
  4. sh MAKEDEV snd1 (there is a reason for using snd1 instead of snd0)

After doing the above, cd to / and put the following lines in your /kernel.config:

	pnp 1 0 os enable irq0 5 drq0 0 drq1 1 port0 0x220 port1 0x300 port2 0x388
	pnp 1 1 os enable port0 0x201

Then add these to /boot.conf:

	load /kernel
	load -t userconfig_script /kernel.config

After doing the above, reboot.

While booting you should see your soundcard detected unless there is something wrong.

PnP SoundBlaster Pro

Note: Make sure you know your irq and dma for your soundcard.

Put the following in your kernel configuration:

	controller  pnp0
	controller  snd0
	device sb0      at isa? port 0x220 irq 5 drq 1 vector sbintr
	device sbmidi0  at isa? port 0x330
	device opl0     at isa? port 0x388
	device awe0     at isa? port 0x620

Then compile the new kernel, install, and reboot. When it comes back up, do the following:

	cd /dev
	sh MAKEDEV snd0

Then cd to / and put this in your /kernel.config:

	pnp 1 0 enable os port0 0x220 port1 0x330 port2 0x388 irq0 9 drq0 1 drq1 5 
	pnp 1 1 enable os port0 0x220
	pnp 1 2 enable os port0 0x620 port1 0xa20 port2 0xe20

Put this in /boot/boot.conf or /boot/boot.rc (the latter is for the latest boot loader):

	load /kernel
	load -t userconfig_script /kernel.config

Once again, reboot.
