For comparison I am running the 32-bit and the 64-bit version of WSJT-X v2.1.0 
GA concurrently. PWR sliders of both versions are set to about 50% (= -20.1 dB 
transmit digital gain). To reach in both cases the same TX PWR output at my 
Yaesu FT-991 I have to increase Windows Volume Control from 7 for all the 
32-bit versions (and for 64-bit until 2.1.0-rc7) to about 80 for the new 64-bit 
GA release of WSJT-X. Although with that the audio level can be adjusted, this 
means a big difference in digital audio gain between the two versions. What may 
cause this difference? Is there another bug in QT 5.12.4? Or might there be a 
defect in the new 64-bit GA version of 2.1.0?

Yes. 

 

Tune power also.

Many thanks for the new GA version! Works well so far here on my computer
(64-bit Windows).
One observation: With the new 64-bit GA version I needed to increase PWR
slider from around 50 % to now nearly 100 % to get sufficient audio level at
my FT-991. Old settings resulted in a few mW TX output. Will do some further
tests, but seems to be reproducible.
Anyone else experiencing that with the 64-bit version?
