In the Stella programmer's guide it says in the section about
PAL/SECAM conversions that you'll get an obnoxious hum on
SECAM, if you try to turn off the sound by setting AUDCx
to 0 instead of setting AUDVx to 0. This is probably what
Dennis is thinking of. There are no problems with PAL sound,
and there is no need to turn all three sound registers off
to mute a VCS sound channel. Just setting AUDVx to 0 should
work on all three console types.
