to generate multiple specific tone frequency, i'll really prefer to use the 16 bit internal timer.
Since you know your frequency range... it's a bit easy to calculate the according period you'll need. Use this period to get the according timer interrupt and VOILA.
OR have a variable external Oscilator and vary the frequency using a digital potentiometer like those microchip MCP42010 or else...
I figure SOUND statement is mostely use to drive piezo transducer.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
