great job man thanx allot

Another option:

#!/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_${driver}
if [ -c /dev/mixer0 ]; then
echo "A driver was found : 'snd_${driver}'"
echo "Add the driver to /boot/loader.conf'"

echo "## Added by the detect_sound script" >> /boot/loader.conf
echo "snd_${driver}_load=\"YES\"" >> /boot/loader.conf
exit 0
fi
kldunload snd_${driver}

Thanks but why did the script load all the other snd modules as well?

Just snd_hda.ko and sound.ko usually do the trick.

If I remember correctly: I think loading sound.ko loads everything under the sun. Loading snd_hda.ko without loading sound.ko anywhere will load sound.ko as a dependency of snd_hda.ko while booting, without loading all of the snd modules.

[lme@]

Yup, DutchDaemon is right.

If I'm not mistaken it's snd_driver.ko that does this not sound.ko.

[DutchDaemon]

Yeah, I think that's about right. Anyway: only load the snd_ driver you need, nothing else. There's a bit of background here (http://www.openaddict.com/node/32).

I noticed that it was the case on i386. Now that I'm running AMD64, kldload'ing sound.ko, doesn't load all the extra modules.

[DutchDaemon]

I believe SirDice was right: it's snd_driver.ko that pulls everything in.

[ph0enix]

Another option:

#!/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_${driver}
if [ -c /dev/mixer0 ]; then
echo "A driver was found : 'snd_${driver}'"
echo "Add the driver to /boot/loader.conf'"

echo "## Added by the detect_sound script" >> /boot/loader.conf
echo "snd_${driver}_load=\"YES\"" >> /boot/loader.conf
exit 0
fi
kldunload snd_${driver}
done

This script loaded snd_ad1816 for my card. The module that's been working for me is snd_hda. I'll test it with snd_ad1816 though to see if that works too.

Sorry, I should have read all the replies before responding.

Thanks so much for posting this script! It made it so much easier getting sound working.
