Soundblaster Live 24bit . I'm going to do a fresh install in a few hours . With the latest build I had OSS enabled and no mixer showing with Kmix . The really frustrating part was that I had sound briefly while compiling SDL mixer and a mixer , but the sound would lock shortly afterwards .

Some notes from FreeBSD FAQ on "sound devices":

http://www.freebsd.org/doc/en_US.ISO885 ... sound.html

You may need to know what chip is on your SB card so you can pick the right driver. Notes from the FreeBSD Hardware compatibility list say that the snd_emu10k1 driver is the correct one. See the notes at

http://www.freebsd.org/releases/6.2R/ha ... html#SOUND

Quote:
The snd_emu10k1(4) driver supports the following sound cards:

* Creative SoundBlaster Live! (EMU10K1 Chipset)
* Creative SoundBlaster Audigy (EMU10K2 Chipset)
* Creative SoundBlaster Audigy 2 (EMU10K2 Chipset)
* Creative SoundBlaster Audigy 2 (EMU10K3 Chipset)


But you might want to look at the following forum topic addressing a problem similar to yours. The suggestion was that the emu driver was not the right one for soundblaster:

In a terminal, as root, you can issue the kldstat command to find what kernel modules are loaded. Look for the module with a name like your soundblaster chip:

Code:
#kldstat

You must include the correct driver in /boot/loader.conf:

First run

- KDE boots , no sound , no mixer , OSS not enabled at startup

-enable OSS and reboot . Sound at KDE startup , still no mixer . Ran Amarok & get "xine was unable to initialize any audio drivers."

- open Kcontrol , choose OSS as mixer and restart sound system .
"Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (Device busy)
The sound server will continue, using the null output device."

- #kldstat sscore.ko and audigyls.ko loaded

- at this point I'm wondering why sound worked with the previous version after pkg_adding OSS and now it will not work with it built in . The Soundblaster Live being a common card and the problem being reported before release , this should not be happening .

-should I try uninstalling OSS and try Linux ALSA ? Trying port installs like this with the lastest build crashed my system .
