First is to figure out if its the system speaker on crack or some bad mixer setting. If its the system speaker and X is making it happen:

xset b off

If it the system speaker and just the running system is doing it, it could be a bios event, power management gone kazoo maybe? Try nulling out anything powery in BIOS.

If its in X, well, fire up a GUI mixer and mute everything, if it kills it, bring it all up one at a time.

Cheers,

Oh and if none of the above works, check "dmesg", the one thing you left out from above

It might have some sound event whimpering in it...

i found the source of the simptom: the "PCM" (what is that?) in KMix - when its enabled and over 3/4 "raised" it creates the beeeeeeeeep sound that "evolves" in much worser sounding beeping sound (changes frequency) as i raise the bar more.

THANKS for the tip finegan!!!

i dont want to stop here - i want to learn and anhilate the problem thats causing the the PCM to make the horible sound, especialy as i need to record some stuff of the tape deck and this could cause problems..i forsee

TIA!!!

You probably don't need PCM, you've got powered speakers right? Check out what PCM means, I can't really remember and a good googling would beat my half-arsed recolection. You can probably mute the puppy.

Cheers,

i have been tolled that pcm is the main sound controll bar.
