Just finished a troubleshooting session with operator setting up Xiegu G90. He was struggled with no audio from the transceiver. Turned out that it was due to the mode setting; it should be set to “U-D (upper side band digital)”. Older firmware like mine (1.75?) doesn’t have this option and works on regular USB (upper side band).

Other relevant G90 settings: line out level, line in level, and input source (line in for digital).  
Tour of older firmware settings for digital modes:

I worked on this for 2.5 days I was using USB as soon as I changed it to U-D it took right off. Thank you for the help.

On mine, pre-software upgrade, JS8Call would put out audio on the first USB transmission, and then all subsequent transmissions would have no actual audio output most of the time. I upgraded firmware and selected U-D, and it now works.

Unfortunately it seems that FLRIG hasnt caught up to the new firmware, and U-D cannot be set through FLRIG. It has to be set by pressing the mode button on the radio. This precludes remote operation by VNC. If anyone has found a fix for this please let me know.

You can add custom commands in flrig, I added a button for l-d and u-d  
go to config, setup, commands  
then for 1, i have label usb-d, command xFE xFE x70 xE0 x26 x00 x01 x01 x01 xFD  
for 2, i have label lsb-d, command xFE xFE x70 xE0 x26 x00 x00 x01 x01 xFD  
type those 2 commands exactly as I have. this will give you 2 buttons under the A tab of your extra commands (down arrow bottom left corner of flrig)
