opengd77 problem with external microphone

Hi guy's,
I noticed that with the latest firmware opengd77 (March 10 but also with the version of March 6) by connecting my external microphone marked "Radioddity" when I press the ptt after a couple of seconds the radio does not transmit and the orange LED lights up . Yes orange, not red ... I had never seen the LED of that color before. I have tried with the stock firmware of the radioddity and the microphone works correctly. I have also tried it on other radios and everything works regularly. Any idea?
I attach the picture of the microphone.

There are not separate connections for the external mic to the CPU.

This must me a hardware problem

I have the same problem, with the older firmware versions it worked fine.
Thank you.

Tried yesterday with one of my cheap microphones, no problem at all (on battery, only).

Cheers.

Maybe different HW versions?

Load the NA7Q firmware to test if the problem occurs.
So far it works fine, I keep testing it.
Because with the openg77 firmware, for periods of time it works well
