I have a box which on occasion starts to emit an annoying whine from the speaker.
It seems that this starts with disk activity (because the disk LED is seen to flash
at the same time), though not with all disk activity. Of course, it may simply be
that the disk activity is simply the loading of whatever process starts the beep.
But what should start a beep ? And not finish it ?
[Background hardware information for the uninitiated : the PC's standard speaker is
driven by a free running timer which is programmed by whatever application to run
at a frequency of X Hz. There is NO duration of a beep - the timer is started, the
speaker emits the noise of the appropriate frequency, and continues to do so until
the timer is stopped by the application (or another application). My problem is
that something starts the timer and does not stop it. I can stop it by doing
"echo ^G >/dev/console" but I'dlike to know what's happening. The box is an ASUS
motherboard with a K6 processor. It's currently running 2.2.5 but the problem also
existed with 2.2.1. Any ideas would contribute to the peace and quiet of my office,
not that there's much of that :-(
