Sound Card just isn't working

Sound Card just isn't working

I've read the HOWTO's; I've read the Readme files; I even read the book
that came with the Slackware Linux CD I bought, and so far nothing's
helped.  Here's the story:

I'm trying to get my sound card to work.  I have a (I'm quoting from my
hardware manual) "8- or 16-bit data: Sound Blaster and Windows compatible,
up to 44.1 kHz audio stereo" card.  I've compiled my kernal to include the
driver for SoundBlaster, and I've set up my device files in /dev.
The bootup messages indicate that the setup is correct (no error
messages), and I've double and triple checked to see if the sound device
files are all set up correctly; The major and minor numbers match up with
what the Sound-HOWTO file says they should be.  I've checked the
/dev/sndstat file, and that seems to be set up properly.  I've made sure
the settings for the card were correct (0x220 irq 7 drq 1).

So after I got everything set up, I downloaded the sound kit for linux
onto my computer.  I executed the following command (as root):

        cat endoftheworld > /dev/dsp

And the resulting error message is:

        cat: write error: I/O error

After looking at the troubleshooting guide and trying to see what the
problem was, I was unable to nail the problem, so I finally used the last
resort: posting a question on this newsgroup.

If anybody knows what the problem is, or think they might know but need
more info from me, reply to me (through email or on the newsgroup).

Thanks in advance!

But it doesn't say "hardware compatible", and probably isn't.  You
should figure out (by reading for hardware specs in the manual, or
visual inspection of the card and comparison with the sound driver docs
just which "compatible" chipset your card really uses.

This is essentially pointless, since in Linux the parallel printer driver
uses polling mode, thus it doesn't need any IRQ at all. If you check
the boot messages with "dmesg | more", you'll see something alike

lp1 at 0x378, using polling driver

No IRQ needed.

The question is what chipset this soundcard is actually using.
Perhaps the output of "cat /dev/sndstat" would be helpful, too .
