I have been unable in my attempts to get QBasic to be able to sample sound
(specifically my CD player playing a cd) via &H20.  The script I am using:

From "The Revolutionary Guide To QBasic" by Wrox Press:
---
CONST screenmode = 12, xmax = 640
CONST BaseAddr = &H240
CONST commaddr = BaseAddr + &HC, DataAddr = BaseAddr + &HA
DEFINT A-Z
DIM byte(xmax)
SCREEN screenmode

DO
    OUT commaddr, &H20
    PRESET (i, byte(i))
    byte(i) = INP(DataAddr)
    PSET (i, byte(i))
    i = (i + 1) MOD xmax
LOOP
----

If I have winamp or any program open using WaveMapper, I get an error that
the sound card is already in use and that I cannot "play the sound."  If I
am using my CD player, nothing happens except a straight line.  The program
is supposed to be an oscilliscope of sorts.  My sound cards base address is
240 (CONST BaseAddr = &H240), but I have tried using 220 and a range of
other numbers.

Can anyone provide some insight into this problem, what might be wrong
and/or how I can get it to work?
