Original description

What steps will reproduce the problem?

1. load and run a tone example script, f.e. toneMelody.pde

What is the expected output? What do you see instead?

You can hear the melody correctly on a Arduino Duemilanove with ATmega328.
On a board with ATmega8 you can only hear one tone (NOTE_B3 I think??).

What version of the Arduino software are you using? On what operating
system? Which Arduino board are you using?

Arduino018 on Windows 7. myAVR USB MKII board with ATmega8 3.6864MHz Quarz.

Please provide any additional information below.
Only the following frequencies give a correct signal: 61Hz, 244Hz, 976Hz, 3.9KHz. Any other frequency gives no signal (PWM output signal measured with oscilloscope)
