My sound works with these commands, but how do I configure sound on startup?

Hi,

I've been struggling with my sound for a few hours now, and I'm really close to a solution.

If I enter these commands, my sound will work until I reboot.

sysctl hw.usb.uaudio.default_channels=6
(then I unplug and replug the USB speakers)
sysctl hw.snd.default_unit=8

This is my /boot/loader.conf

nvidia_load="YES"
linux_enable="YES"
snd_driver_load="YES"

this is my /etc/rc.conf:

hostname="decibel"
ifconfig_em0="DHCP"
ifconfig_em0_ipv6="inet6 accept_rtadv"
sshd_enable="YES"
powerd_enable="YES"
# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="NO"

hald_enable="YES"
dbus_enable="YES"

gdm_enable="YES"
gnome_enable="YES"

They are Bose Companion 5 USB speakers. How can I automate this?

Thanks!

Okay, now I've added this to my /boot/loader.conf

hw.usb.uaudio.default_channels=6
sysctl hw.snd.default_unit=8

but I get a buzzing sound while booting up. The buzzing stops when I log in to GDM.

 

[BLuFeNiX]

alright, I got it!

nvidia_load="YES"
linux_enable="YES"
hw.usb.uaudio.default_channels=6
hw.snd.default_unit=8
snd_driver_load="YES"

I had to load the sound driver after I configured the other stuff, otherwise I got a buzzing noise. This configuration works flawlessly.

Don't use snd_driver. It's just a convenience thing, it simply loads all available drivers. Find out which one you need and load only that one.

You should probably use

snd_uaudio_load="YES"

Instead of

snd_driver_load="YES"

You can also write those sysctls into /etc/sysctl.conf which only loads them after the system enters multi-user-mode.

Oh, alright. Thanks.

I'm going to assume that this is what SirDice is talking about, I'll try it. Thanks.

Does that provide any speed increase or benefit if I'm booting straight into my DE? Thanks.
