soundcard is not recognized on slack 12 (old hardware)

MsDoomshroom · 04-28-2008, 03:18 PM

I am using Slackware 12 on a Toshiba Tecra 730XCDT. I have been using it for a while and just realized a couple of days ago that I have no sound.

this shows no sign of the sound card that should be detected.

I have changed the bios menu settings involving sound to every possible configuration. And have reinstalled Slackware a few times and sound works with other distro such as DSL.
I have searched for drivers to install with Google. I find drivers for cs4232 for windows but not linux. I have found a few threads and articals that were insightful but all required that the hardware be recognized by the kernel to begin with before the trouble shooting could begin. This is an issue that is a little above my level of experience to troubleshoot.
Does anyone have any suggestions?

What about lsmod? What does it show?

From /usr/src/linux/Documentation/sound/oss/CS4232:

Quote:

To configure the Crystal CS423x sound chip and activate its DSP functions,
modules may be loaded in this order:

modprobe sound
insmod ad1848
insmod uart401
insmod cs4232 io=* irq=* dma=* dma2=*

This is the meaning of the parameters:

io--I/O address of the Windows Sound System (normally 0x534)
irq--IRQ of this device
dma and dma2--DMA channels (DMA2 may be 0)

On some cards, the board attempts to do non-PnP setup, and fails. If you
have problems, use Linux' PnP facilities.

To get MIDI facilities add

insmod opl3 io=*

where "io" is the I/O address of the OPL3 synthesizer. This will be shown
in /proc/sys/pnp and is normally 0x388.

Google showed up this:
http://www.astro.umd.edu/~teuben/lin...710.html#sound

I suggest that you experiment with inserting modules with appropriate io, irq, dma and dma2 settings. Once you get it working, add the required lines to /etc/rc.d/rc.modules.

Hi,

What happened when you ran 'alsaconf' from cli as root? Did you store the setup with 'alsactl store'?
