View Full Version : intel ac97 sound does not work and lspci and lsmod commands not available

I have a compag presario B1800 latptop that is about 1 year old and being disillusioned with the direction Microsoft is goingwith Vista, decided to install FC6. I was able to get my intel wireless working after checking some posts but not my sound.

I've updated my alsa drivers to version 1.0.14rc1

I've re-run the command system-config-soundcard and it shows I have the intel 82801FB/FBM/FR/FW/FRM ICH6 AC'97 sound card but it still doesn't play sound.

Having seen posts that suggests running the following commands to get some more diagnostics
lsmod | grep snd
the response I obtain is not what I expected:
bash: lsmod: command not found

I also tried running the command
lspci | grep -i audio
and got this:
bash: lspci: command not found

I don't want to go back to Windows but have to admit this - I can't do without my music. I hope someone can give me a solution that's simple enough for me to implement.

hi,

it looks like you need to be root to run those commands.

type
su -
enter your password then try those commands again

Cheers, I wondered if I ought to have mentioned that I had already entered the su command prior to entering the commands that failed. As I had typed su already, any other ideas as to the cause of the problem?

su -
don't forget "-"

Hi, I was elevating myself to root prior to entering the commands.

So my commands are

# lsmod

# lspci

and they don't work

Hi guthers,

As davfel and virus have said above, you have to enter "su -" not just "su". The dash fixes your path so that you can run commands from /sbin and /usr/sbin.

Alternatively, you can type the following:

$/sbin/lsmod
$/sbin/lspci

Thanks danwaineo,

I don't know what I'm missing when I enter "su -lspci" I still don't get the result so I tried your alternative and have the following output. I hope this may lead to a way to get the sound working.

I don't know what I'm missing when I enter "su -lspci" I still don't get the result
"su -" and "lspci" are two separate commands. First do "su -" and give the root password, then do "lspci" in the same terminal window. Finish with "exit".

I'm not an expert but here's a troubleshooting guide for alsa.

http://alsa.opensrc.org/TroubleShooting

Also, aplay can be used to test. $aplay -l will list your sound devices:
http://alsa.opensrc.org/Aplay

You might also want to check for alsa related error messages in your messages log.

Finally, I read somewhere that modems can interfere with sound cards, and you might want to turn off your modem in bios. If that is the problem I think you should get an error message in your log.

Hope this helps a little. I found these site while trying to get my sound card working. I don't think mine is supported yet, but yours should work.
