I'm finally getting around to playing with sound (largely because dosbox
choked over its absnce when I went to play an ancient game :)

Anyway, this is a Compaq Presario F767NR--a basic disposable sub $500.
(For anyone searching for this model, the wifi works with Sam's updated
HAL, and the binary driver for X installs easily.)

Anyway, I checked the hardware list at
http://www.freebsd.org/releases/7.0R/hardware.html
and it appears that snd_hda is the appropriate choice, but

redtail ttyp2:/root# kldload /boot/kernel/snd_hda.ko
redtail ttyp2:/root# kldstat
Id Refs Address Size Name
1 12 0xc0400000 63bdc0 kernel
2 1 0xc0a3c000 711edc nvidia.ko
3 2 0xc114e000 28494 linux.ko
4 1 0xc1177000 6a2b4 acpi.ko
5 1 0xc61f6000 14000 snd_hda.ko
redtail ttyp2:/root# cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <NVidia MCP67 High Definition Audio Controller> at memory
0xf6480000 irq 21 kld snd_hda [20080420_0052] [MPSAFE] (1p:1v/1r:1v
channels duplex default)
redtail ttyp2:/root# ls /dev/dsp /dev/pcm*
ls: No match.

The hda driver is indicated for nVida MCP65A and MCP65B, as well has
generic chipsets supporting hda.

Oh, and from dmesg,

pcm0: <NVidia MCP67 High Definition Audio Controller> mem
0xf6480000-0xf6483fff irq 21 at device 7.0 on pci0
pcm0: [ITHREAD]
pcm0: <HDA Codec: Conexant (Unknown)>
pcm0: <HDA Driver Revision: 20080420_0052>

For the kernel config, I've added,

# sound
device sound
device snd_hda

Am I missing something obvious again?

thanks

I haven't read this closely, but one thing worth checking is whether
loading snd_driver will show you that another driver can attach to the
device.

That's how I found snd_hda.

After unloading everything, it seems to be what comes back:

redtail ttyp2:/root# kldload snd_driver
redtail ttyp2:/root# cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)

channels duplex default)

Okay, good. What exactly is the problem?

The lack of /dev/dsp or anything else that I can recognize as an audio
device. According to the handbook, it should be there.
