Without knowing what way Knoppix doesn't like your sound chip it's 
difficult for us to know whether it's software or hardware related.
Here is the basic steps you can take regarding any hardware problems.

First use the tools at hand. When you are using Windows identify
the sound card using the device manager. Jot the down name of the 
card/chip then interrupt it is using and the port hex range.
I know what you are going to say "Oh so i have to use Windows to
fix a Linux problem". :-} Actually you don't but since you are new
to Linux you use the tools at hand.

Next time you boot Knoppix, open up a terminal session and at the
command prompt type.

cat /proc/interrupts

What you should see is something like below exept the asterisk is mine.

           CPU0       
  0:    1976414          XT-PIC  timer
  1:       4543          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  8:          1          XT-PIC  rtc
  9:      11865          XT-PIC  es1370       *
 10:          0          XT-PIC  uhci_hcd
 11:         32          XT-PIC  eth0
 12:       2432          XT-PIC  i8042
 14:       8287          XT-PIC  ide0
 15:      17136          XT-PIC  ide1
NMI:          0 
LOC:    1976418 
ERR:          0
MIS:          0

The line infront of the asterisk is the sound card module. The first
number is the interrupt it is using the second tells me it is active
and the es1370 is the module the sound card is using. The module
usually resembles the manufactures name. In this case it is an Esonic
sound chip. Compare it with your Win setup. If it's the same then
things are looking good. The next thing is to see if the sound
modules are loaded. Issue the command.

cat /proc/modules |less

nfsd 210272 9 - Live 0xd0f12000
exportfs 4672 1 nfsd, Live 0xd0e40000
es1370 30252 1 - Live 0xd0e2d000                   *

I have cut this down for brevity. The |less part of the command
will allow you to scroll up and down as the print out can be 
rather long. If you see anything like the lines by the asterisks
then it is telling you that the sound card, sound and as an aside
your game port modules are Live (activated). If so far things are
looking good then it's reasonable to assume that there is probably 
nothing wrong with your sound setup. There is one more command
you can use on a normal Linux setup but apparently not with
Knoppix.

cat /proc/ioports |less   

0170-0177 : ide1
01f0-01f7 : ide0
0200-0207 : es1370  *
02f8-02ff : serial
0376-0376 : ide1
03c0-03df : vesafb
03f6-03f6 : ide0
03f8-03ff : serial
d000-dfff : PCI Bus #01
e800-e8ff : 0000:00:0f.0
  e800-e8ff : 8139too
ef00-ef3f : 0000:00:12.0
  ef00-ef3f : es1370 *

Again this is cut down for brevity. This gives you the address
range of the sound port and should match your Windows settings.
I'm sorry if this looks a bit long winded but in reality it 
only takes a minute. You may wish to save this message as a faq
as it is a good way of trouble shooting some hardware stuff 
including your etho card.
