Sometime around the 6th of February in 1999, a certain Ben Luey said:

: I have a soundblaster awe-basic 64. I'm noticing a lot of static coming
: out via the line-out port. I believe the problem is with the sound card
: because when I turn off the sound (cut volume to zero) via software all
: the static goes away. When I turn up the volume it comes back, even when
: I'm not playing any sound (pause on a cd, etc). Is there anything I can
: about this? Or is it normal to hear static when the volume is medium-high?
: Could this be software related? (I started noticing it around the time I
: upgrade my kernel to 2.2pre6, but I only got my new speakers a few weeks
: before that).

: Thanks,

: P.S. How do I control the volume of the speaker from the terminal? The
: only way I know is with wmmixer or another gui program. Is there device I
: need to cat a number to?

I found a little util (on Sunsite, I think) called 'mix' that controls the
mixer device from the command line. I dunno where it is on Sunsite, but
I've got it at ftp://ftp.jellyd.org/pub/linux/sound/mixers/mix-1.0.tar.gz
.

I usually just use it in conjunction with this script to max out all the
sliders (sometimes my sound card likes to change them, and I like to
control the volume externally with the speakers anyway):

#!/bin/bash
echo 'Attempting to change mixer device values...' > /dev/console
mix vb=100 > /dev/null 2>&1
mix cb=100 > /dev/null 2>&1
mix pb=100 > /dev/null 2>&1
mix lb=100 > /dev/null 2>&1
mix sb=100 > /dev/null 2>&1
echo 'All sliders set to maximum setting.' > /dev/console
