Oops.. I copied link from browser window and it did not work. you need to type it as http://e-www. and so on, see previous message, or just search motorola.com for MC33215. Good luck.

MC33215 has analog volume control, see datasheet at
http://e-www.motorola.com/files/timing_interconnect_access/doc/data_sheet/MC33215.pdf
You can use a digital potentiometer from Dallas (www.maxim-ic.com), connecting it between VOL pin (pin34 or pin35, depending on package) and ground.
