I think you are right and I made a mistake there. In OS/2 you used install the Audio driver and on the DOS VDM you configure the session so it can pass the sound to the OS/2 driver and hardware. It had been a long time since I had configured OS/2 on an old hardware that is supported by OS/2 and DOS.
