Here is a simplified functional diagram of an 8-bit DAC. Some vocabulary: DAC:Digital to Analog converter. D0, D1, D..: Data lines. Analog: Continuous electrical signals. Digital: Method of representing information using “1″ and “0″ (usually 5v and 0V). LSB: Less significant bit. MSB: Most significant bit.

I didn't go through all your maths but an 8-bit audio isn't going to sound too good. You're going to have to bias to half-supply which leaves you with 7-bit on each side. You may get away with this on compressed speech where dynamic range is severely limited but quiet passages of speech or music will have terrible distortion due to the coarse step size and the ear's logarithmic response.

In a short, an eight bit DAC or typical low resulution PWM can't provide good sound quality. I would consider some recent audio codec chip. They have programmable sample rates starting from 8 kHz and resolutions from 16 bit.
