Button Mod, are there other free gpios for analog reading?

[baesek]

Hi,
regarding the Button Mod which uses Pin 36 as PIN_KEY_ANALOG for analog button reading
like this:

adcAttachPin(36);
analogReadResolution(10);
analogSetAttenuation(ADC_11db);

Does anyone know which pins can be used as Analog Input without destroying wifi capabilities?

Are there any Pins that can be used without doing the button mod?

EDIT:
On my board with the button mod I tried the following Pins with this result:
/*
PIN 36 -> working
PIN 13 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 19 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 23 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 18 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 5 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 21 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 22 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 23 -> audio is fucked up (beep tone underneath the audio) whne using this as analog pin
PIN 25 -> No audio at all.
PIN 0 -> No audio at all.
*/

EDIT2:
It seems that it is wrong to just call this code a second time to setup another analog Input:

adcAttachPin(uint8_t pinNr);
analogReadResolution(10);
analogSetAttenuation(ADC_11db);

if I edit the button_setup function like this:

void button_setup()
{
#ifdef AUDIO_KIT_BUTTON_DIGITAL
    // Configure keys on ESP32 Audio Kit board
    for (uint8_t i = 0; i < sizeof(buttonMap); i++) {
      pinMode(buttonMap[i], INPUT_PULLUP);
      buttonStates[i] = HIGH;
    }
#endif
#ifdef AUDIO_KIT_BUTTON_ANALOG_OLD
    adcAttachPin(PIN_KEY_ANALOG);
#ifdef TEST_ANALOG_PIN
  adcAttachPin(TEST_ANALOG_PIN);
#endif
    analogReadResolution(10);
    analogSetAttenuation(ADC_11db);
#endif
}

There is no beeptone at least for Pin 13, but the range is also 4096 instead of 1024 then.

EDIT3:

My further investigation on which Analog Pins could be used lead me to thinking:
-Only Pins of ADC Channel 2 can be used if wifi should still work. (source : https://randomnerdtutorials.com/esp32-adc-analog-read-arduino-ide/)

• that means only the pins of ADC1 can be used:
  33,32,35 -> Could that one work? But how can we access it ? Sound works if I set it up as an input in the code.
  36 -> Key AD -> Analog Input for Keys
  39 -> HP Detect -> Headhpone Detect -> Can this one be used without making it impossible to use headphones?
  34 -> SD Detect ->Sd Card Detect -> Can this be somehow used even if an sd card is used, by modifiyng the sd card code? this is anyways only read on boot... I don't need hotswapping sd cards.

Thank you!!!
