6 channel sound no sub


Hi There,

I have an Asus A7N8X-E DELUXE motherboard, and i'm using the onboard sound.
Front and rear channels work great but nothing is coming out my sub/ centre channels. (i'm just plugging my normal speakers into that channel for the moment to test it - thats ok is it?

I've checked the KMix settings.... everything is high, nothing is muted

Any ideas how to get my sub going?

Cheers
Jack

I'm assuming you have the alc650 onboard card..

do you have the bracket for the sub/centre?

or do you have to plug into the line in and mic for you 5.1 sound?

Check in the Kmix settings, click on advanced

and select mic as center/lfe?

Cheers,

Gary

this one actually has the whole lot on the motherboard. 3 usual outputs + SPDIF + rear out + sub/centre out.

I've run into similiar problems with other sound cards, especially the newer ones.

Often the solution was documented in the kernel sources for the sound card drivers.

Have a look.

Look in the corresponding directories under

/usr/src/linux

That has the kernel sources.

Remember you can grep an entire directory or set of subdirectories very quickly to find the target files.

Try this, (where XXXX is the name of your sound card drivers, etc...)

e.g. for SBLIVE as root.


find /usr/src/linux -exec grep -l XXXXX {} \; | more

This tells the OS to FIND all files which exist in /usr/src/linux including those which exist in subdirectories.

Then on each and every file it runs the grep command against what "find" locates (the {}) looking for XXXX within the file and only listing the file name (the "-l") and then passing the result to "more" which will show you only one screen full of results at a time.

You can then view each file in turn if you wish.

It sounds like you do not have a complete Mandrake installation as urpmi is a required component.

That or you did not attempt to do this as root.

If you didn't log in or SU to root and try this command again.

If it fails you may want to consider re-installing/upgrading it again.

(An upgrade would potentially fix this..)

urpmi is an "intelligent" installer.

When you issue the command, it automatically goes out and downloads any other missing components that may be required to get the package you want to install to run. These are called dependancies.

You could manually install the urpmi package

rpm -Uvh urpmi*.*.rpm

from the source CD's but that it is missing normally indicates a bigger problem.
