I am running Fedora Core 1 on an Aopen MK79g_Max with Nforce2 chip using the Nvidia drivers.I am having trouble with sound matching video in RealPlayer.It's a 1/2 second off synch.

The Helix/RealPlayer people asked me which sound drivers I'm using.I don't see the drivers listed anywhere.I only see a AC97 codec device listed under my sound card hardware.

Where do I look and for what will it say.Will it spell out alsa or oss?

the command you want is lsmod (list modules)
it can be run as ordinary user

alsa drivers tend to start with snd_

alternatively

(not sure whether the "redhat-config-sound" command is still part of the fedora series, but it might be worth a go - it might give the name of the audio driver/s)

Well I have tried playing with "lsmod".I used it in a terminal and all I get is "lsmod command not found".I see everyone using that command shouldn't it be installed by defualt.I used the standard install with my Fedora disks.I tried switching to root (did "su" "password") still no such command.I must have modules right?I believe my Nvidia drivers needed to be loaded as a module.

try /sbin/lsmod

the "su" command gives you root access rights but you stick with the normal user environment...
the root user has a differend path variable than normal users in fedora (root's bath has the "/sbin" entry, notmal user doesnt...

get into the habbit of using "su -" instead of "su" this will also give you root's environments aswell as root's privilages.

O.K. I have a lsmod output now.The "su -" allowed to use the command.
It looks like this

[root@localhost root]# lsmod

I'm still not quite sure which is my audio driver.
I assume it is one of these?
i810_audio 27048 1 (autoclean)
ac97_codec 17064 0 (autoclean) [i810_audio]
soundcore 6500 2 (autoclean) [i810_audio]

If so am I running three sound drivers?Is this a conflict?

maybe there is a way to tell what these modules are?(or maybe some resources)

i810_audio 27048 1 (autoclean)
ac97_codec 17064 0 (autoclean) [i810_audio]
soundcore 6500 2 (autoclean) [i810_audio]

List all three in reply to the Helix people and see what they say.
