You know who had released his evil mosquito to the public during TED. Beside Malaria, mosquito also spread deadly dengue fever, West Nile Virus, Enchepalitis, filaria (worm) etc.

Is there any Linux sound application that can turn the idle speakers into mosquito repellent?

Another way is emulating the sound of predators that hunt mosquito / insects.

This may not help you much, but that buzz you're hearing is just the "sixty-cycle hum". Any speaker will produce this unless you have a noise gate in place between the source and the amp.

Code:

SOURCE --> {PRE|POST} AMP --> OUTPUT

* SOURCE = Computer/guitar/CD player/something that outputs a signal
* AMP = Wherever the SOURCE connects to
* OUTPUT = Speakers

I used to get a terrible hum from my old tube amp for my guitar - I was even picking up my neighbours' telephone conversations. Then, I got a processor pedal for Christmas, one year, that included a noise gate - no more mosquitoes.

The only thing I can think of is to check each cable and connector in the circuit from your computer to the amp, and then to the speakers.

I think he is saying he WANTS to generate that noise

Quote:

Mosquito generates high frequency sounds ranging from 16kHz to 20 kHz to keep away mosquitoes

couldnt you just use one of the simple soft sythns in linux like zynaddsubfx or alsa modular synth to create a simple sine wave at around 16kz to 20 khz and then use sample and hold to have it just play forever or untill you shut it down??

You have mosquitoes in your house ? Why not install some nets for windows and doors ?

That high frequency sound can damage your ears with time you know. It also doesn't work too well, I've tried lots of those stupid emitters and none of them work well.
