Sound card

Revision as of 04:28, 1 August 2005

In order to get sound out of your FreeBSD box, you'll need to either load your sound driver module or compile sound support in your kernel -- it's not installed by default. For this you need to use kldload to load your sound driver. If you don't know which sound card you have -- and therefore don't know which driver to use -- you can load the generic snd_driver module (in 5.x systems -- in 4.x you need to load the snd module), which works for most cards, like so:

samizdata# kldload snd_driver 

If that works, you'll probably want it to load automatically at boot time. To do so, you'll want to append a line about snd_driver to your loader.conf:

samizdata# echo snd_driver_load="YES" >> /boot/loader.conf

And presto, when booting, your system will always try to load snd_driver.

FreeBSD5.4 Sound

In FreeBSD5.4 they changed the sound system a lot and now to install sound under FreeBSD you have to do the following:

 freebsd# kldload sound

Then find out your sound card. I'm using an ASUS A7N8X motherboard with Nvidia onboard sound so I typed

 freebsd# kldload snd_ich

Then when I had tested this and it worked I entered the following into my kernel:

device sound

device snd_ich

and recompiled
