Weld wires for the analog audio output

Hi sorry for my bad english…

I have Banana pi BPI M64 with operating system “2017-08-14-ubuntu-16.04-mate-desktop-beta-aarch64-bpi-m64-sd-emmc”. I removed the connector and soldered the wires but did not sound out. Did I weld the threads in the right way? Thank you
