Is your real machine really DOS?
Because if you're running XP (for example), then you'll NEVER be able to turn off sound for the whole machine.
Mean U if I run win Xp , I will cant turn off sound?
but for example aplication run on dos
If you're using a crusty old compiler like TurboC then you're stuck.
On XP, DOS runs in a virtual machine (playpen, sandbox, whatever you want to call it). The point is, there is NO WAY it can affect the whole machine.
To do what you're suggesting, you need a Win32 compiler which is compatible with your main OS (and not just some emulation for the benefit of older things).
Windows NT based systems dont like you writing programs like that
Windows 9x and DOS wouldnt mind, but salem is right. A TSR to terminate sound wont run on NT, regardless of whether it is run in a command prompt or not. This is not a real dos prompt, but an emulation.
And yeah, turboc is ancient. Please stop using it.
