Anyone make, or have suggestions for, an automatic audio switch...

Made something like that in ancient times around a HEF4060 and 2 HEF
4053's.

It would scan inputs, if audio present, it would stop the 4060 clock.

Second 4053 to drive one of the 4 leds. (OK, I had a load of 4053's,
had to use them up..)
