To be honest the longer i think about this the less sense it makes for a few reasons...
What other reasons are there then, because I did deselect the sound references (take the speaker symbol out) from the control panel - sounds and audio section.
Coming back to the Hardware Devices, these are the only drivers left in the "sounds and audio" section that I can deinstall:
LITEON CD-ROM LTN4865 Type: DVD/CD-ROM (of course I'll leave this)
Audiocodecs Type: Audio-, Video- and Gamecontroller
Legacy-audio driver Type: Audio-, Video- and Gamecontroller
Media control device Type: Audio-, Video- and Gamecontroller
Legacy-Videorecorddevice Type: Audio-, Video- and Gamecontroller
Videocodecs Type: Audio-, Video- and Gamecontroller
In my point of view, only the Audiocodecs, Legacy-audio driver and media control device could be removed to try and stop the beep noise... or just the first two?
I doubt whether this will actually cut off the bugging beep noise alltogether though
