Maybe the following VBScript "port" of the above will work:

-- check_soundcard.vbs
rem Check for a working sound-card - exit with 0 if OK, 1 otherwise.
set wmi = GetObject("winmgmts:")
set scs = wmi.InstancesOf("win32_sounddevice")
for each sc in scs
    set status = sc.Properties_("Status")
    wscript.Echo(sc.Properties_("Name") + "/" + status)
    if status = "OK" then
        wscript.Quit 0 rem normal exit
    end if
rem No sound card found - exit with status code of 1
wscript.Quit 1

-- eof

Running "cscript.exe check_soundcard.vbs" and checking the return code
should work.  cscript.exe comes with all modern Windows variants, and
although there may be ways to install Windows without it, I think we can
safely assume it exists for these purposes.
