disable sound, how?

Post by jumpstation.co.u » Mon, 26 Nov 2001 04:30:09

in a nut shell; I had pcmcia working, setup sound and now it does not.

full details;


I am running debian 2.2.18 on a compaq lte 5000.

It has no CDROM drive so I use a pcmcia external which has worked from day
one with no configuration.
I have spent sometime getting a pcmcia compact flash card to work and
adventualy it mounted fine as vfat.

Since then I have got sound working as a soundblaster compatable.
works fine but now the pcmcia CDROM and compaq flash. can not be mounted.
(note: a pcmcia 3com network card never has any problems.)

When inserting either CDROM or the flash into the PCMCIA slot I get one high
beep and then one low beep and NO futher
information as aposed to the normal two high beeps and a read out of the
type of card on the console.
when running "cardctl ident" both devices are recognised as they should be
but i can not mount them. (i tried one at a time)
mount gives an error about /dev/hdc being not recognised as a block device
and a comment "(maybe 'insmod driver')".

lsmod clearly lists all the correct pcmcia bits.

my guess is that the PCMCIA used to use irq 5 (or some other resource) and
now the sound card has taken that and will not give it back.

cat /proc/interrupts
0  timer
1  keyboard
2  cascade
5  sound blaster
8  rtc
12 ps/2 mouse
13 flpu
14 ide

and I exclude 3,4,5,7 in /etc/pcmcia/config.opts

The default settings in config.opts (which worked previously) are

include port 0x100-0x4ff, port 0x800-0x8ff, port 0xc00-0xcff

include memory 0xc0000-oxfffff
include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff

I tried excluding the "port 0x100-0x4ff" as the SB uses 220 to no avail.

I tried to remove all traces of the sound via
rmmod sb
rmmod uart401
rmmod sound
rmmod soundcore
rmmod soundlow

and although this clears the /proc/interrupts 5 still no luck

What else could be holding sound settings that are conflicting with the
PCMCIA stuff ?

what do ide block devices mounted from PCMCIA normal use for irqs ?

can i tell the soundblaster to use a different irq ?

any ideas ?


1. How do I disable sound in KDE

How do I disable the sound of my KDE environment?  If I'm
logged in via an X terminal, I don't want the actual machine,
which is on somebody else's desk, to make noises every time
I do something.
Actually, it's not making noise now.  It's getting permission
denied errors every time it tries and dumping them to stderr,
which is also annoying.
I just want it to stop trying, but I can't find any place to set
