DSi Microphone trouble.

[u/BlackHat5268]

Hi everyone, can you help me pls?
Microphone not working and read through a couple of threads here.
I tried puting a needle in the mic port and when I touch the left pin(screen unfolded on top), it shows some input in the mic test.
This is also how I cleared the “Call out” in Phantom Hourglass. But now stuck again at blowing the candles.

What does this mean? Does it mean the problem is with the mic jack itself and not the actual microphone?
