Hi.  Im have set up my DRAWS hat/FT817 according to "temporarily Offline" youtube video.

Install good
WSJT-X good
CAT good\ - PTT band change etc.
RX good - waterfall/decode etc great.
I set my WSJT-X audio to in/out toplughwCARD=udrc.DEV=0
Seems my only problem is audio from HAT to FT817 as while rig goes to TX, no audio drive.
Radio is all OK as I use it for Win/FT8 SSB etc.

I do not know where to look for audio output drive adjust on the Pi/HAT/WSJT-X steup

I am new to all this and learning.

Any help would be gratefully received.
