Sound on pfSense 2.0.1

pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router.

I got it running inside an Alix2d2 board.


Sometimes, with the help of a cron daemon and mpg123, I use this device as alarm clock. I attached a USB soundcard and loaded the proper kernel modules to get It working. Then, I installed mpg123 from the PKG repos. As last step, I added the “cron” package with the pfSense package manager.

First, copy the neccesary modules to /boot/kernel/. You can grab a copy of these kernel modules from here

First, copy the modules to /boot/kernel
admin@pfsense:~ # uname -a
FreeBSD 8.1-RELEASE-p6 FreeBSD 8.1-RELEASE-p6 #0: Mon Dec 12 18:59:41 EST 2011 i386
admin@pfsense:~ #
admin@pfsense:~ #
admin@pfsense:~ # cp sound.ko snd_uaudio.ko /boot/kernel/
admin@pfsense:~ # chmod +x /boot/kernel/*.ko

To load audio and USB audio support run:

admin@pfsense:~ # kldload sound.ko
admin@pfsense:~ # kldload snd_uaudio.ko

To load these modules at startup, add then to the loader.conf file:

admin@pfsense:~ # /etc/rc.conf_mount_rw
admin@pfsense:~ # echo ‘sound_load="YES"’ >> /boot/loader.conf
admin@pfsense:~ # echo ‘snd_uaudio_load="YES"’ >> /boot/loader.conf
admin@pfsense:~ # /etc/rc.conf_mount_ro

You can check the sound status with kldstat,/dev/sndstat, etc.

admin@pfsense:~ # kldstat

Check the FS status. If you are running pfSense on a router board like me, you will need to remount
the FS as read-write (as I did then copying the kernel modules to /boo/kernel).

admin@pfsense:/root # mount -v
/dev/ufs/pfsense0 on / (ufs, local, noatime, read-only, synchronous, fsid 8c96e64e3f8508d2)

Add the mpg123 package with the pkg_add command.

admin@pfsense:~ #
admin@pfsense:~ # pkg_add -r
Fetching… Done.
Fetching… Done.

Try mpg123!

admin@pfsense:~ # mpg123 -h
mpg123: Missing argument for option "h".
You made some mistake in program usage… let me briefly remind you:

Finally, I added this cron entry for the alarm clock 😀
