Default Permanently Change Default sound device.

New FreeBSD 7 Amd64 install with an AMD SB600 Southbridge.

pciconf shows:
Code:
pcm1@pci0:0:20:2:	class=0x040300 card=0x10131019 chip=0x43831002 rev=0x00 hdr=0x00
    vendor     = 'ATI Technologies Inc'
    device     = 'IXP SB600 High Definition Audio Controller'
    class      = multimedia
Portions of dmesg"
Code:
pcm1: <ATI SB600 High Definition Audio Controller> mem 0xfe8f4000-0xfe8f7fff irq 16 at device 20.2 on pci0
pcm1: [ITHREAD]
Code:
acd0: DVDR <LITE-ON DVDRW LH-20A1S/9L03> at ata5-master SATA150
pcm0: <HDA Codec: Unknown Codec>
pcm0: <HDA Driver Revision: 20071129_0050>
pcm1: <HDA Codec: Realtek ALC883>
pcm1: <HDA Driver Revision: 20071129_0050>
SMP: AP CPU #1 Launched!
The default sound device is /dev/dsp which points to
Code:
$ sysctl hw.snd.default_unit
hw.snd.default_unit: 0
If I change hw.snd.default_unit to 1 all is good but I lose the change on the
next boot. How do I make this change permanent? ?/boot/device.hints?

Thanks in advance

Is that /etc/sysctl.conf?
What is the syntax for the entry?
I'm guessing
hint.hw.snd.default_unit=1

Thanks

This is what ended up working in /etc/sysctl.conf

Code:
hw.snd.default_unit=1
Thanks for your help.

If your not sure about the syntax of a configuration file, you can usually find details in the manual

man conf_file_name (e.g. man sysctl.conf)

or a reference to the proper manual page in the programs own manual under the SEE ALSO section.

/usr/share/examples and /usr/local/share/examples if memory serves also has some nice things.
