cable - mono device to android

[k4kaleem]

Hi All,

i need to capture audio from an external amp into android.

I made a cable which connects mono out to mic, got a normal 4 pole to 4pole cable, chopped halfway then joined speaker from Source to mic on recorder side (Android phone)
its working fine but i have couple of issues and needed help to find a better stable solution

1: audio has noise, any way to cut it? (to be honest i can live with it, its not extremely critical, point 2 is more)
2: i have noticed weird behaviour, if i plug android side first then it uses the cable to record audio but if source side is plugged in first then android cable then it doesnt detect and uses builtin mic only.
is there any way or official cable i can use, this is quite annoying as this setup is not mostly used by tech people so they can plug cable in wrong sequence and app not to work.
thanks in advance.

I believe Your phone is detecting / measuring low resistance (speaker resistance).
Try with a resistor in series say 1K.
Make sure You are using the right cable since there are two standards, which swap Mic & GND.
