Did you have to program the IC (not the multiplexer)? Also if I want multiple inputs, I'll probably use a bigger multiplexer but will it still work with the IC?
Here is: my-gnuradio.org/wp-content/uploads/2017/10/audio_switch.png Small note about this schematic: because 4052 IC has internal channel resistance, sound on an output lower then input signal.
@@bsdmry is there a reference anywhere for the values of the resistors and capacitors? And maybe the code that’s running on the Atmega8? I plan on doing my own project with a few CD4052 ICs but with Curcuitpython. I see you’ve tied VEE on the CD4052 to ground. So it’s running in DC that way? Are the capacitors on the outputs there to counter DC bias?
Wow, love this circuit. How did you decide what value capacitors to use on the output?
Can you help me in developing 8×8 8×16 and 8×32 Multi room audio matrix switcher ?

Hey dude... What is the switching chip that handles the momentary pushbutton logic? Is that some sort of microcontroller?
Yes, as shown in the description, it's CD4052 multiplexer and Atmega8 microcontroller
Hello, can you share the schematic? That would be awesome

Bro what power supply did you use for muxcd4052
The simplest way: 5V from USB
Nice project, compare 4066?
Hello
Ic Atmega8. You burn data in arduino ?
No. It's a pure C code + avr-gcc compiler. Atmega IC flashed by avrdude using raspberry pi gpios
