Question lkm - keyboard don't sings as well !!

I'm programming a kernel module.
this module use the call request_irq() to install a personalised routine (ISR)(
this routine will setup the PPI (8255) and the timer (8253) for send a signal to the speaker

in brief , I want the speaker plays a note when a key is pressed

my problem is that the speaker don't stops to play.

the 2nd problem is that I whould like to know if it is possible to store in some variable the address of the old rountine !?
