If you can find a chip that needs 7.88mhz on pal and 8.18mhz on ntsc
then sure, but you're then just using the DOT clock as a cheap way of
getting a clock.

This used it for that exact reason

~8mhz is kinda high for a sound chip though. Even 1mhz is incredibly
high for producing sound in the human audible rangle.
