	Several replies on my problem with the SID noise confirm,
	that there is a problem.  Among other's comments, the noise
	is digital and probably due to the SID sharing the same
	ground as the micro circuits.  So if you are experiencing
	the same problem, programming the both the oscillator and
	volume simultaneously is the best software cure. A possible
	hardware cure is to disconnect the common ground as the
	Commodore manual says it is (but it's not).

				Good Luck

	I'll try the latter and post the results. Thanks to all
	who responded.
