I have several remarks about the sound driver.
First of all I'm getting the following warnings each time I make it.
Here are the warnings when I've make it as module in the linux-1.3.69:
make[2]: Entering directory `/home1/ftp/pub/linux/kernel/v1.3/linux-1.3.69/drive

If needed I can post the .depend file...
Also my sound card is a SB 16 ASP. I prefer to have the micro gain at 0
by default and to use the LINE input as my record device.
Here are the diffs in drivers/sound:

Why not to make a /etc/'sound_default' file with de default settings for the
sound mixer? Each time the sound driver is loaded it could read this
file to get the settings.
