MotoTRBO with MSA Sordin

[KMB]

I got a problem for my MSA Sordin with my XPR6550.
When I key the Nexus U-94/A PTT in digital mode, it will go out "Bump.....Bump....." at another side. However, it works OK when in analog mode.
What am I setting wrong?

You are using a non-sanctioned audio accessory and I don't think it'll ever work properly.

Oh～～～ but some tried and said it works～～～…>_<…
