Any thoughts on what I am doing wrong ?
I have a :
OS : Debian GNU/Linux 13 (trixie)
OS Kernel : 6.12.62+rpt-rpi-v8
Asterisk : 22.7.0+asl3-3.7.1-1.deb13
ASL [app_rpt] : 3.7.1
the sound card is modified as per How to Modify A CM108 Sound Fob For Allstar 2. - allstar setup.com
I have a Motorola gm300 no matter what config i do i can’t get the radio to ptt the sound card i get receive from the sound card to the radio , i cant get an out ptt /core , the voltage are correct from the gm300 here is how the config is setup and i tried multiple confg and still not working
GM300 cor is active low (it does not change if i go active high)
the following is what i have for sound card configuration
I have included both the simplusb and the usbradio file below
here is the simpelusb.config:

;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
; jbenable = yes ; Enables the use of a jitterbuffer on the receiving side of an
; simpleusb channel. Defaults to "no". An enabled jitterbuffer will
; be used only if the sending side can create and the receiving
; side can not accept jitter. The simpleusb channel can't accept jitter,
; thus an enabled jitterbuffer on the receive simpleusb side will always
; be used if the sending side can create jitter.
; jbmaxsize = 200 ; Max length of the jitterbuffer in milliseconds.
; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is
; resynchronized. Useful to improve the quality of the voice, with
; big jumps in/broken timestamps, usually sent from exotic devices
; and programs. Defaults to 1000.
; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of an simpleusb
; channel. Two implementations are currently available - "fixed"
; (with size always equals to jbmax-size) and "adaptive" (with
; variable size, actually the new jb of IAX2). Defaults to fixed.
; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".
