SD card Audio Shield is not being recognized with TFT connected. Otherwise it work

[ronsut]

I made up this module to test the code for a SDR transceiver project that I am working on. There is a conflict between CS track to the 3.2 TFT (with ILI9431chipset) and the Audio shield so I have cut the track to the TFT as shown and redirected the CS track to pin 17 leaving only the Audio shield on PIN 10 of the Teensy 4.0

The test code I am using is taken from the Audio Tutorial and modified for the 3.2 TFT with
the TFT CS pin10 is the code also changed to pin 17 and DC to pin 9 to reflect my test board layout.

Maybe a better picture of the soldering would help.

Thanks for your reply
I did not review my post before uploading it. When I read it the following day it did not make much sense to me, so I was not expecting a reply.

I found the problem, the issue was in my code, #define TFT_RST 255 instead of 8. I don't know why I changed it from the original example code.

Yes, the photos did not help.
