mexus:
TimerFreeTone v1.4 and the example doesn't work for me. No compile errors.
No sound at all. Using one of your other libs or standart tone works.
I need no timer sound, or using timer0 (pins 5 or 6) without breaking time functions.
I need pins 9,10 and 3,11 for high frequency PWM
You can't use timer 0 without breaking time functions, so your only option is using TimerFreeTone. Are you using the example sketch and not getting sound output? Have you tried using a different pin (A0 is a good one to try). The example is using pin 10, which you should avoid as you're doing something with the PWM.
Anyway, my guess would be a timer conflict, and simply using a different pin would work. But, I'd need to see your sketch as well as a description of how you have things connected. I'll verify everything works later today, but I believe the example sketch works without a problem.
