[linrad] Re: Sound problem under Debian's Sarge



I was going to tell you some directions, but I am not sure if they are accurate cause they are based on my woody-sarge mixture machine. So, I am going to work on my new fresh sarge install (in the spare partition) and I will tell you.

Obviously you do not need to reinstall (this is a wrong windows habit ;-) ).

I am going to tell you some hints that can avoid some nightmares for you:

The configuration of modules is strange at the begining, but soon you will understand that it is a very eficient way of doing things.

In Debian with 2.6 kernel, the configuration of modules is  on the
/etc/modprobe.conf file . But if you look at it, you will see that /etc/modprobe.conf "includes" the file /lib/modules/modprobe.conf. If you go to and edit /lib/modules/modprobe.conf you will see that Debian say :"you should not edit this file"

Well, instead, you must go to the /etc/modprobe.d/ directory

There, you will see some text files. That files include the configuration of the modules. When the root user runs the utility "update-modules", every file on /etc/modprobe.d/ directory is parsed, and a new /lim/modules/modprobe.conf is created. This is a very convenient way of doing it. When you for example install a new Debian package, and it needs a new module, its internal scripts create a new file in /etc/modprobe.d/ directory containing the configuration of the needed modules. The, the package installer runs "update-modules" command and the new module is included in the setup.
Easy, is not it?

So, the files on /etc/modprobe.d directory are the files that you need to tweak.

This is a very general aproach. I am not sure if the utility included in the alsa-utils package ("alsaconf") have a program to configure the sound easier with needing to know this compications. Any way, it is recomended to know how Debian works internally to get full control of the system.

I am going to play a little with my fresh sarge install to confirm this.

See you again.
Ramiro.

Hello Ramiro and all,

I have some problems with my audio system on the Debian's Sarge :

When I installed the system, the only audio board on the system was the
motherboard's built-in VT8237. Everything looked fine until I started
Linrad. The 'U' command give me the choice between 2 different boards,
both named '00' with the same VT8237 chipset.

The soundcard test mode give a sort of square signal with the
corresponding sound in the speaker...

I suspect a misconfiguration in the audio system that reports false
informations to Linrad, but I have no way to solve the problem.

I disabled the motherboard's audio device in the BIOS, and put a good
old Creative's ES1371, to see if this could not solve the problem , but
I do not know how to install it....

Well, that is my sound card.


Now Linrad reports no sound device. How could I change the audio board
without re-installing Sarge (It's fun but ...)

Very 73
Patrick
