I am trying to set up sound on fedora core 4 and a toshiba satellite a70 laptop. I founfd this on a site about setting up fc3:

SOUND:
Edited /etc/hotplog/blacklist and added
snd-atiixp-modem
trying resolves the sound card problems.
I also got rpm -i alsaconf-0.4.3b-1.noarch.rpm but I now forget what problem I was trying to solve.
Still no sound: I did
modprobe snd-atiixp
Got sound, so I added the above line to /etc/rc.d/rc.local
It now works, but run aumix to get all the volumes up.

I also found this on a site for setting it up on the a75.

Sound

Sound is supported through Alsa and the snd-atiixp module. In Windows, it's identified as AC97 sound; apparently there are several chipsets associated with this, and for this laptop, the corresponding module is snd-atiixp.

One problem if you use hotplug is that both snd-atiixp and snd-atiixp-modem are loaded by the hotplug script and sound doesn't work.

Solution is to add snd-attixp-modem to the hotplug blacklist file at /etc/hotplug/blacklist. Actually, I added both snd-atiixp and snd-atiixp-modem to the blacklist script and added "modprobe snd-atiixp" to /etc/rc.d/rc.local. After that, rebooted and ran as root "alsaconf", which set up /etc/modules.conf with the appropriate commands identifying the soundcard. Then used amixer to unmute the sound. I also added commands to unmute the mixer controls to rc.local so this runs when the laptop starts up:
amixer set Master 90% unmute
amixer set PCM 90% unmute

this is the output from lsci.

So, I did everything in the first one, and nothing happened, and in the second one, it said it used alsaconf, but I don't know what driver to choose. Can someone help me?

Never mind, unmuted everything in alsamixer and it worked.
