There might be some possibility...
Old version of RUFZ (CW rainer) did not support the sound card. Then 
DL2OAP 
wrote the following program to support 
the sound card.
Put this in the wish list?

RFZSOUND.EXE  v1.3a  by Thomas K”n, DL2OAP              
(translated by DL4MM)

Introduction:

The software RUFZ by DL4MM is a 
quit popular Contest- res. CW-training-
program. A certain disadvantage of this 
program is, that sound-output is only 
possible via the built-in PC-speaker and 
the meanwhile very often used 
soundcards are (still) not supported. A 
hidden built-in speaker in a PC-tower-
case under the desktop makes it 
difficult to copy higher speed and 
not 
everybody likes to connect a headphone 
inside the computer. After discussions 
with RUFZ-power-users there was the wish 
to use a present soundcard.
In a "weekend-project" the following 
described program RFZSOUND was written. 
It bases completely on RUFZ, it just 
replaces the speaker-procedures by own 
procedures controlling the soundcard.

Program-Description:

To embed the new procedures, RFZSOUND.EXE 
is searching for certain code 
sequences inside RUFZ.EXE and replaces them 
at two points by a call of two 
software-interrupts (7EH and 7FH, usually 
unused). The attached interrupt-
routines are part of RFZSOUND and 
providing control of soundcard. After the 
initialisation of soundcard modified RUFZ.EXE 
will be re-started as a child-
process. After the end of RUFZ.EXE 
all modifications are revoked. This means, 
after the end of RFZSOUND the normal 
RUFZ.EXE will be in original shape 
and 
can be used like before (in case 
you are yearning to the sound of 
a PC-
speaker). Please note - there are 
absolutely no modifications on the timing 
of 
RUFZ ! The CW-speed is NOT 
influenced. Also the different tone-frequencies 
are 
taken over correctly. ( All scores 
with RFZSOUND are valid for RUFZ-Toplist 
..
