Could be using the wrong driver.. In my mixer selection stuff I don't have any AC97 capture settings. Sounds like maybe your using generic sound card drivers.
The SBLive = Sound Blaster Live! with the 5.1 surround support?
Could definately be the wrong drivers. My Audigy and the Soundblaster live! 5.1 should use the emu10k1 drivers.
I am sorry, but i am not to familar with Mandrake's graphical configuration tools. The commands may be "missing" because your user's path may not be pointed to their directory. The PATH is a enviromental variable that tells the OS the locations of your executables.
If somebody tells you to go:
sudo commandname
or log in as root by going:
su
log in as root instead by adding a dash behind the su command like this:
su -
This tells the OS that you want to use root as if you logged in originally as root, and that will setup all the enviromental variables and paths and such that are appropriate for a root user. Just using "su" without the dash tells it to just keep everything as if your a user, just with root administrator rights. "superuser".
If that still doesn't work and you need to find a command, try using "locate". Locate uses a database that is built up of your filing system to quickly look for files. It's built up every evening so new changes may not go into effect until updatedb is ran. If your looking for newly made files you can use find, which is quite a bit slower, like such:
locate commandname
find / 2> /dev/null |grep commandname
I assume that Mandrake has gui configuration tool for the drivers. Set it up so that your using the Alsa drivers for your your card. Then open up a terminal and use the "su -" command.
Then go:
lsmod |less
lsmod will list all the modules currently in use by your kernel. The |less part just makes it so that you can scroll up and down it using the arrow keys. Look for the module name.
"emu10k1" is the module name for the OSS drivers.
"snd-emut10k1" is the module name for the Alsa version.
Once you determine that your using the correct snd-emu10k1 module then try to use "alsamixer" to configure.
On mine to setup snd input capture on line in you go and turn up the "line" slider. Then you go and find the two "Analog M" sliders. One is the Analog Mix, and the other is Analog Mix Capture. If you turn up Analog Mix you should here the sound input, turn that down and turn up Analog Mix Capture and that will be the setup to use for Mythtv to capture it. Then make sure that none of the first few sliders and your analog capture and line in are not past 80% or so to aviod distortion.
If it's not using the correct snd-emu10k1 driver, then see if you can trick it buy telling it that it's a Audigy.
As for the RPM stuff check out:
http://www.redhat.com/docs/man...l-guide/uninstall.html
The way to remove rpm packages are
rpm -e packagename
however, I would wait to do that till you tried everything else. Removing the rpms could cause Mandrake's configuration stuff to glitch out and force you to use command line only stuff. Also it could confuse urpmi because it does dependancy checking and it won't have any way of knowing that you installed alsa software from source manually.
maybe for a much better/quicker/more correct answer check out the forums at
http://www.mandrakeusers.org/ chances are that somebody already had your problem and solved it and will have a quick easy step by step answer on how to fix it. Do a quick search, and if you can't find the answer then ask. You can't be the only one setting up Mythtv and SBLive is about the most common card in existance.
I am not a big Mandrake fan, and unfortunately I can only take it from a very generic linux standpoint.
