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 ..
