This entries have changed, though the function is the same.
[USRP]
address = 127.0.0.1                     ; IP address of USRP partner (Allstar/Asterisk or another Analog_Bridge)
txPort = 31001                          ; Transmit USRP frames on this port
rxPort = 31001                          ; 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_UNITY                  ; Analog -> Digital (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
tlvGain = 0.35                          ; Gain factor when tlvAudio = AUDIO_USE_GAIN (0.0 to 5.0) (1.0 = AUDIO_UNITY)

show us your Analog_Bridge.ini file. even in the cloud you should have those entries

These lines were not in my Analog_Bridge.ini file.  There were tlv and usrp entries that were similar....messing with those, but so far, no increase in DMR audio into the TG.

This is a setup of two analog VHF and UHF repeaters with the intent of adding a DMR talkgroup through a cloud server.  It works, but DMR audio coming out to the TG from the repeaters are very low.
