Mine is a very high-pitched permanent noise which is definitely well above 8 kHz (the highest frequency my doctor's listening test equipment would check, and no notch here - I would have suspected a certain masking effect but fortunately, nothing - fingers crossed). Does anyone know about a good ALSA compatible tone generator which I could use to find the peaks? My sound card (well, a 24/96 one, ummm ...) and my Sennheiser 580 phones should be able to provide a near-flat frequency response up to about 20 kHz... -- A bird in the hand is worth what it will bring.
