Log in as root.
Open a terminal window.
Enter the following commands:
hwinfo > t.tmp
less t.tmp
The hwinfo command may take several minutes to run. When you enter the less command you will should see a listing of all of the hardware on your system. The list is extremely detailed. See if you can find the Audigy sound card in the list. Then enter the following commands:
lsmod | sort > t2.tmp
less t2.tmp
You will see a list of all of the hardware drivers. There are several for the sound system. This is the listing for my system related to the sound system:
snd 62212 12 snd_seq_oss,snd_seq_midi_event,snd_seq,snd_pcm_oss,snd_mixer_oss,snd_via82xx,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device
snd_ac97_codec 65668 1 snd_via82xx
snd_mixer_oss 18944 1 snd_pcm_oss
snd_mpu401_uart 8064 1 snd_via82xx
snd_page_alloc 11656 2 snd_via82xx,snd_pcm
snd_pcm 93832 2 snd_pcm_oss,snd_via82xx
snd_pcm_oss 56872 0
snd_rawmidi 25636 1 snd_mpu401_uart
snd_seq 55312 4 snd_seq_oss,snd_seq_midi_event
snd_seq_device 8456 3 snd_seq_oss,snd_seq,snd_rawmidi
snd_seq_midi_event 7680 1 snd_seq_oss
snd_seq_oss 31360 0
snd_timer 25860 2 snd_seq,snd_pcm
snd_via82xx 27812 0
soundcore 9056 1 snd
You can see the entry above for snd_via82xx. That's the driver for the sound chip on my motherboard. The computer that I'm using to write this doesn't have an Audigy. Anyway you should see an entry in your listing for the Audigy driver.
Lastly if all else fails do this:
Shut down the system and power off.
Remove the Audigy card.
Power on.
Enter BIOS setup.
Make sure that the motherboard sound system is disabled.
Reinstall Linux.
Shut down and power off.
Insert the Audigy card.
Power on and boot Linux.
Log on as root.
KDE will probably say that it found a new hardware device, the Audigy. It should ask if you want to configure the Audigy. Say yes.
I have found that it is sometimes a good idea to install Linux in a bare system and add cards after Linux is running. Only add one card per reboot.
