It sounds like there is a TSR conflicting with AAPLAYHI. Try starting with a
"clean boot" and see if the problem goes away.
To clean boot, rename your config.sys and autoexec.bat files. Create a new
config.sys with only the bare necessities… FILES=xx BUFFERS=xx, etc. In your
autoexec, load up your mouse driver.
If this works, begin adding in your drivers one by one until you find the
culprit.
