what does it mean???
should read out & print analog value's of mux???
Exactly when and where are you seeing this output ?
Please post your sketch and a schematic of your project. A photo of a hand drawn circuit is good enough
If I open serial monitor it print this text directly & keeps on printing the same..
I'll post my code directly & a wiring diagram..
I've got esp32 & meaning is I read out 2 mum's with 32 sensors connected to it.
I've got a ws2812 led matrix.
if a sense goes above the given threshold it needs to light up 2led's of the led matrix.

wiring diagram: hope it's a bit clear to understand...
for the moment I've just did 1sensor & 1multiplexer...
I'm testing at the moment with only 1 sensor & multiplexer but I doesn't start up anything, just the print in serial monitor but nothing more..
I just so that the drawing in photo is wrong... on the IR diode's I've did black & red wrong..
GND line (black) needs to have the resistor and go to the mux..
Red (5v) line goes directly to the 5V battery..
WS2812 led in drawing is single led, but in circuit it's a 8x8 led matrix..
power lines are not drawn but is connected to 5v & GND off esp32
GPIO_NUM_8 is the FLASHD1 pin and should not be used.
GPIO_NUM_6,7,8,9,10, & 11 are special use pins.
Problem remains the same after I swap pin8 to 19..?
Include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.
Post below the code changes you have made.
Are you sure the LED strip likes being open circuited when the multiplexer switched its input?
BTW this
is not a problem
it is "working" now...
but doesn't do what I expected to do.. 
I've connected 2channels to mux... ch02 & ch 14..
led's 28&29(ch14) remain on and leds 4&5(ch02) remain off..
if I read out sensor without multiplexer there supposed to be at 0 when its dark in the room (its dark for the moment...) when I emit light value goes up en corresponding leds light up...
but with multiplexer value's are through the roof... changing constantly from 101-809..
I do not know. You don't really give much to go on. Did you try seeing if the mux inputs were all grounded you got all 0's and if the mux inputs were all sent high you got all highs?
Common man, you've made at least 15 posts already asking for help. Have'nt you learned by now what is needed to help someone help you?
Also the leds light up white instead of blue & red..?
I've changed the output from 19(digital) to 0 (digital/analog) but still the leds remain white..
does wiring & soldering affect the analogRead value's?
cause I've been testing without wiring just on breadboard & there my value is 0 when I expect it and goes up when I expect it to..
since I've connected the mux & wired it, value's aren't anymore what I expected to be..?
I don't know what you need? I've provided code, schematics & what my problem is??
what info can I provide you with so you can help me? tell me & I'll try to do so..
if mux is connected to ground it indeed give's out 0's en when connected to high input it goes high.
but when I wire everything up, it don' get the value' s I'd expect & I've received when testing on breadboard
