Default Sound on FreeBSD

Setting sound up on FreeBSD is quite simple and well documented but here's a simple how-to.

There are two ways to add sound support to FreeBSD - compile the driver into the kernel or dynamically load the driver. I'll just detail the latter as it's faster and easier.

First you will need to load the driver, if you know the driver name, you can load it straight away. If not, load the whole lot and hope one binds.

Depending which version of FreeBSD you are running it will be :
# kldload snd
or
# kldload snd_driver

If you have loaded all the sound drivers with the above command, you can see the specific driver you have loaded by doing the following

#cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <VIA VT8237> at io 0xb400 irq 22 kld snd_via8233 [MPSAFE] (5p:1v/1r:1v channels duplex default)

In this case snd_via8233 is the driver being used.

To make sure this driver loads on boot, you'll need to edit /boot/loader.conf. In this case i would put the following in this file:
snd_via8233_load="YES"

If you want all the drivers to load ( for whatever reason ) you can put the following in loader.conf
snd_driver_load="YES"

* Note: if anyone notices any errors in this how-to, please correct them

Here is a script that will load the sound drivers one by one, detect which one you're using, and add it to /boot/loader.conf.

This will work on any version of FreeBSD.

Code:
#!/bin/sh
#
# Detect sound driver

for driver in /boot/kernel/snd_*; do
  driver=$(echo ${driver} | sed 's|/boot/kernel/snd_||')
  if [ ${driver} = "driver.ko" ]; then
    continue;
  fi

  kldload snd_${driver}
  if [ -c /dev/mixer0 ]; then
    echo "I'm smelling 'snd_${driver}'"
    echo "snd_${driver}_load=\"YES\"" >> /boot/loader.conf
    exit 0
  fi
  kldunload snd_${driver}
done

Nice shell script. Any chance on seeing a "BSD Scripting 101" guide or a post with some useful tutorials?

starbuck - i don't mind writing one but it's hard when there's so much to scripting - PM me and we'll organise something

starbuck.

IMHO your probably going to learn more from reading a manual like Unix Shell Scripting Third Addition By Sams.

OT (sort of) learning material suggestions:

I'll second the suggestion to pick up a book as reference material. Personally, I really liked Sams Teach Yourself Shell Programming in 24 Hours (2nd Edition) by Sriranga Veeraraghavan. (I'd write a review on it, but someone at work stole it and I haven't read it in a couple years...)

Also, check out the Advanced Bash-Scripting Guide from TLDP. Just keep in mind that sh != bash, exactly.

I have a page with some links that *I* found useful.
http://home.nyc.rr.com/computertaiju...scripting.html

As was said, bash isn't shell, so think about keeping your scripts portable. For example, I wrote something on a Linux box that starts by checking if you're root. I used $UID instead of id -n, not realizing it was a bash-ism. (errm id -u, whatever.) We have some AIX machines as well, and that caused me a bit of embarrassment.

If you run pciconf -lv as root and examine the results (I suggest using a pager), you will likely be able to identify some info: also look at the dmesg.

If there's any specific issue, you might want to launch a thread for it.

The following would be your card, indeed no driver currently claims it, yet.
Code:
none0@pci0:0:31:5:	class=0x040100 card=0x434d1849 chip=0x24c58086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Realtek AC97 Audio (82801DBM SoundMAXController (ICH4-M B0 step))'
    class      = multimedia
    subclass   = audio
This handbook page indicates that kldload snd_driver will attempt to load several common drivers, did you try that?

A full list of sound card drivers can be found using apropos or man -k on a FreeBSD system, but here is an online list.

My bet is snd_ich(4) or less likely snd_hda(4).

Hope that helps, but, it seems Beastie got here first.

After the initial installation yes, it is empty.

Closing posts isn't common place here, especially considering this isn't even your original topic.
