Thanks for the reply!

1. I ran sndconfig which told me
Code:
A PCI sound card was found in your system. The details are:
Model: Creative Labs | [SB Live! Value] ENU10k1X
...and after the next OK button proceeded to say

Code:
The Creative Labs | [SB Live! Value] ENU10k1X is not supported.
This was sndconfig v. 0.57 (from KNOPPIX_V3.2-2003-07-26-EN, which incidentally boasts "... added another audigy PCI ID -> emu10k1 driver
").

I got a newer version (sndconfig_0.67-3_i386.deb) from debian.org, but couldn't install it (with dpkg) as of course everything is read-only.

(BTW: Would it help to just have Knoppix on a CD-RW to make such changes possible? Or is this not enough, and I would still have to go through all those re-mastering calisthenics?)

2. lspci said this:
Code:
 . . . snip . . .

	Subsystem: Creative Labs: Unknown device 1003
	Flags: bus master, medium devsel, latency 64, IRQ 16

3. ...and lsmod had this to say:
