had sound working, updated machine now lost sound

Mon Aug 26 21:48:42 UTC 2013

Dear all,

Following  advice from  thread(s) :

http://forums.pcbsd.org/showthread.php?t=13976

http://forums.freebsd.org/showthread.php?t=5136

root at grullahighschool:~ # sysctl hw.snd.default_unit=0
hw.snd.default_unit: 1 -> 0

Got the sound working like it was.
How do I get it to stick across reboots?

Which would be the preferred way?
ie,

use file
root at grullahighschool:~ # cat  /etc/sysctl.conf
# $FreeBSD: release/8.4.0/etc/sysctl.conf 112200 2003-03-13 18:43:50Z mux $
#
#  This file is read when going to multi-user and its contents piped thru
#  ``sysctl'' to adjust kernel values.  ``man 5 sysctl.conf'' for details.
#

# Uncomment this to prevent users from seeing information about processes that
# are being run under another UID.
#security.bsd.see_other_uids=0
vfs.usermount=1
hw.snd.vpc_autoreset=0
kern.module_path=/boot/kernel;/boot/modules;/usr/local/modules
You have new mail.
root at grullahighschool:~ #

or place in /boot/loader.conf the line:

hw.snd.default_unit="0"

?

Thanks for helping figure things out.  I had working sound but maybe
updating to 8.4-RELEASE changed things around?

Best Regards,

Antonio
