Question Questions


First post; new too Linux; over 65; no problem partitioning installing various distros of linux. Toshiba satellite P100. Basic question, all works [ wpa ect ] but the sound, if the sound is not supported will it be at some future date?; is there a equivalent of drivers for hardware to download and install?. Ubuntu 7.04 now ; same problem with PClinux. Find the forum difficult to use so if this post [ happy just to have found a place to post :-) ] is not in the right place [ and its probably not ] put little red arrows [ or something or a active link ] showing me where to go.
Thanks
jim :-)

Well, from old guy to another, welcome.

Let me see if I can help.

Quote:
if the sound is not supported will it be at some future date?
Most sound cards, or sound chips work now. The hardware detection is the sticky point. Once we know what sound chip, or card you have, we'll look for the correct module, and load it using the command 'modprobe modulesname'.

In the unlikely event the hardware does not have a module, most likely it would be supported in the future.

There are several ways to determine what card, or chip set you have. The exact best method depends on what you have, so we may need to try more than one to find out.

Open a konsole and run the command 'lspci' ( without quotes ) this lists the hardware connected to the PCI bus. Some laptops and some desktops have the sound chip connected on the system board, and not on the PCI bus. So this will only show your card if it is connected to PCI.

You could also go to the Tosbiba web site, and look for the system documentation, usually under support. There is usually a spec sheet that will tell you what you own. This almost always works, just takes time to find.

Another method, if you have a windoze system still installed, look in the device manager, and it will tell you what you have. Only works if you have windoze installed.

Another method is to get yourself a copy of Knoppix. It is a live CD, burn it, and boot it. Knoppix has the best hardware detection I have run into. If any linux distro will find your card, Knoppix is the best bet. If it works, then just do a '/sbin/lsmod | grep snd' command. That will list the modules loaded by Knoppix. The we know what to load in Ubuntu.

Once we know what you have, it is not too difficult to find the KLM ( kernel loadable module ) that works with your hardware.

Post back what you can discover.

I remember thinking that 65 was old---I'm much better informed now.....

Sometimes, a problem like this is simply a matter of adding yourself to the right groups. eg on my PCLinuxOS install, sound works out of the box. New regular users are in the "audio" group by default. My Ubuntu system is at the moment NOT working. I just added my self to audio, but it didn't "stick" after logout/login---still struggling with that one.

Hi.

If your still not getting any joy, run the following and post the results:
As your normal user:
Code:
id
ls -l /dev/snd/
As root, or through sudo:
Code:
lsmod | grep snd

Thanks for help and suggestions; will get back to you on the chipset ; made another ext3 partition today so will be installing other distros as well. Loving this linux experience so far. Have a new desktop on the way and will just be useing this laptop only when i have too but want it set up and working on linux when i do need it. The desktop will be on linux as well so i may have many more questions; probably a cetainty :-) Thanks again; you will be hearing from me again soon.

About my audio. What i can read says Device auto 82801G [ 1CH7 family ] Also says Intel high defination audio [ AZALIP ] Manufacter Conexant model CTX5047.
Spent about 5 yrs in Toronto, arrived in 59, needed to get back into the mountians of BC though.
thanks; appreciate your help.

Good stuff, I'll do some looking around to see if I figure out what module to load.

Looks like this is what you need to load.

Chip: Intel Corporation 82801G - High Definition Audio
Kernel-Module: snd-hda-intel

I ran the following on my system ( Mandriva 2007 spring ).

Quote:
locate snd-hda-intel
/lib/modules/2.6.17-13mdv/kernel/sound/pci/hda/snd-hda-intel.ko.gz
The locate command turned up the full module name, and path to the module, on my system.

Open a konsole, and do a 'su' and enter the root password. To be able to use 'locate' linux looks in a local database for files, rather than searching the disks. So fist command to run is 'updatedb' ( no quotes, as root ). Then run 'locate snd-hda-intel.ko.gz' If it is there, you will find it. If not, you may have to use your software installer, and install it.

If you find it, then run the command 'modprobe snd-hda-intel' That will try to load the kernel module. No news is great news here. If you get no response, that means the kernel is happy. if it dumps a bunch of stuff, boo! Then we'll have to figure out where to go next.

Next, bring up a mixer, turn up the volume, make sure you are not muted. Then try to play a sound.

I googled '82801G' and got a boat load of hits. Seems a few others are struggling with it also.

Let me know how far you get...

heres a thread on this exact problem.. looks like there are several approaches to fix it. but it comes down to a buggy driver for that chip set that affects it in several different kernel versions..

http://www.linux-on-laptops.com/foru...ead.php?t=1488

looks like the module for that chip set would be "hda - Intel High Definition Audio"

hopefully that will help get you on track..

More questions; are the console and terminal the same thing ? Can't find out how to get to or find the console but can get to terminal. Tried su using terminal and it asked for a password, when i tried to type in a password nothing happened; no letters came up; tried a number of times, same results.??? Haven;t been able to try any suggestions yet.
Thanks again
jim :-)

Yes, the console and terminal are the same thing. Passwords are not echoed not even a * is displayed. So just type in your password and press the Enter key.

Hi Jim,

When you do

su

You need the root password, not an ordinary user password.

Was the terminal prompt (last character) a # or a >?

If it was a # you are already root, and can execute any command in terminal.

What is the kernel version on ubuntu 7.04 and PClinux? (try uname -a). Apparently, the bug in the sound module - if that's what is actually causing the problem - was fixed on 2.6.20.x.

regards.... andrew.

when doing su you should always follow it with a hyphen like so

mycomputer:~/$ su -
password:

if you leave out the hyphen you do not get the user environment you are switching to, in this case root so your $PATH will not get updated and you will get "Command not found" errors when trying to run simple commands that should work without a hitch for the root user.

a better worded explanation can be found here:

Hi Jim,



If I was in your "just starting out" position (still too fresh in my mind), I'd do the following:

1. If the rev level of your kernel is less than when they fixed the bug, find a distribution which has a sufficient rev level.

2. If the rev level is already good, the chances are better than 50/50 that this can be fixed with the GUI (eg your distros configuration / install tools). At least you can find out what the GUI has to say about the card.

I'll probably be criticized for saying that by the more learned folk here who are really trying to help you, so let me apologise in advance if I seem to be implying that the GUI CAN be more productive early on.

regards.... andrew.
