MMDVM_Bridge to XLX #mmdvm_bridge #analog_bridge

I have a bridge from allstar to our XLX reflector. Having some weird audio issues. most stations are solid their entire transmission and some get to transmit for a short time then drop. 

would this behavior be caused by some audio settings or something else? Any thoughts would be greatly appreciated. 


Bellow is my audio settings 

[USRP]
address = 127.0.0.1                     ; IP address of USRP partner (Analog_Reflector, Allstar/Asterisk or another Analog_Bridge)
txPort = 32001                          ; Transmit USRP frames on this port
rxPort = 34001                          ; Listen for USRP frames on this port
usrpAudio = AUDIO_UNITY                 ; Digital -> Analog (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_USE_AGC)
usrpGain = 1.10                         ; Gain factor when usrpAudio = AUDIO_USE_GAIN (0.0 to 5.0) (1.0 = AUDIO_UNITY)
usrpAGC = -20,10,100                    ; Set the agc threshold (db), slope (db) and decay (ms)
tlvAudio = AUDIO_USE_GAIN                  ; Analog -> Digital (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
#tlvAudio = AUDIO_UNITY                  ; Analog -> Digital (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
tlvGain = 0.15                           ; Gain factor when tlvAudio = AUDIO_USE_GAIN (0.0 to 5.0) (1.0 = AUDIO_UNITY)
aslAudio = AUDIO_USE_GAIN               ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN)
#agcGain = .5                            ; Gain (in db) of the AGC filter
agcGain = 1.8                          ; Gain (in db) of the AGC filter
dmrAudio = AUDIO_USE_GAIN                  ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
dmrGain = 0.5                          ; Gain factor of audio from ASL (0.0-1.0)
