Hello I used the software on the hblink3 server. Its working finde but the voice its broken. I test it with hytera RD625 V8.5 and an mmdvm hotspot. RD625 ---> MMDVM sound very god. MMDVM---> RD625 its broken. I test also a Parrot from RD625 the echo its on mmdvm hotspot fine and on the hytera also broken. I check yout from here the actual Master

on Hytera received audio its broken. on Motorola it shows short ID than screen change to standby

maybe something with the air data?

maybe someone knows how I can solve it?

@smarek Hi! Tnx for quick response. Do you have any indication on where in the code we could start debugging?. Got accesses to repeaters and everything :)

I believe order of voice frames is incorrect (or the frames are marked incorrectly in MMDVM/Homebrew protocol, DMRD voice/data and slot bits) You can compare out and in streams or compare with different hytera/homebrew tools (eg hytera homebrew gateway from oe1kbc or any other) I dont have more from top of my head, if you find anything, ill appreciate :)
