[App_rpt-users] tx audio delay

Hello, need some help. Using usbradio and want to know where and how I can make adjustment to delay tx audio between it and PTT. I'm doing something experimental and I am getting clipped (cut short at start) audio. I see it being sent via CLI but the radio isn't in transmit yet. This is only after I issue something from the radio I am using to talk to the node. Otherwise, announcements, cwid and activity is fine. It may be a rx issue, since I am using carrierfrom=vox and rxdemod=speaker. Maybe some conflict where it is using a vox delay or is picking up a tail of false rx... So any place to set these delays? Thanks Greg
