How to add drivers for PCI sound card

[aurora]

I'm trying to install drivers for a PCI Sound Card (Creative Sound Blaster Live) and here's what I did:

# cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <EMU10Kx DSP front PCM interface> on emu10kx0 [MPSAFE] (4p:1v/1r:1v channels duplex default)
pcm1: <EMU10Kx DSP rear PCM interface> on emu10kx0 [MPSAFE] (1p:1v/0r:0v channels)

Added this line to /boot/loader.conf:

emu10kx0_load="YES"

But when I do that and reboot, nothing happens. The sound card doesn't work.

If I add this line to /boot/loader.conf:

snd_driver_load="YES"

The sound card works but

So many redundant drivers out there. It looks to be wrong, doesn't it?

How to run this sound card in best possible way? What line should I add to the /boot/loader.conf? Thanks.

add this line to /boot/loader.conf:

emu10kx0_load="YES"

But when I do that and reboot. nothing happens. The sound card doesn't work.

It's

snd_emu10kx_load="YES"

Or

snd_emu10k1_load="YES"

If I add this line to /boot/loader.conf:

snd_driver_load="YES"

The sound card works but so many redundant drivers out there. It looks to be wrong, doesn't it?

That "driver" actually loads all available sound drivers

It worked. The sound card works after adding this and reboot:

snd_emu10kx_load="YES"

and

 #kldstat
1   13 0xc0400000 a52fc4   kernel
 2    1 0xc0e53000 14d04    snd_emu10kx.ko
 3    3 0xc0e68000 4a5b4    sound.ko
 4    1 0xc0eb3000 62800    bcmwl5_sys.ko
 5    3 0xc0f16000 1ada4    ndis.ko
 6    2 0xc0f31000 e740     if_ndis.ko
 7    1 0xc0f40000 6a538    acpi.ko

It looks fine, thanks.
