Changing volume/mute status permanently?

Distribution: Mandriva 2006
Sound card: Aureal vortex au8820 (vortex 1)

When I turn on my computer, I get no sound in Linux. However, if I run alsamixer and unmute the "Master" and "PCM" controls, then I get sound. However, the changes to these are only temporary; they disappear if I turn off the computer. How can I change these sound settings permanently?

Thanks.

Run, as root:

Code:

alsactl store

To load the settings, run:

Code:

alsactl restore

but chances are that is run automatically with each boot. If it isn't, making it run automatically with every boot isn't difficult.

Thanks, that does work, except it doesn't appear to run "alsactl restore" on startup. How can I make this happen?

Thanks again for your help.

If your running KDE use the KDE mixer (volume control), edit the settings to restore on startup.

Edit one of the init scripts.

Can you give me an example of "one of these init scripts" and where they are located?

in /etc/rc.d/rc.alsa and make it executable.
