My volume experience with 8.351:
With auto-adjust volume unchecked - the volume is about 10% higher, pretty much at the same level as 8.302
With checked - no change from 8.350. The volume no longer auto-adjusts and is MUCH quieter than 8.302.
My suspicion is that, since 8.35x is a dual release for the x20/x30 and for the newer x40 models, they probably tuned the ambient noise calculation for the much better microphone in the x40.
Since the x20/x30 mic is much worse (based on ASR reliabilty) than the x40, I suspect that the software can't hear anything on x20/x30 devices, assumes the background is quiet, and auto-adjusts for what it thinks is a very silent room.
Where is that selection made? I went through all the menu options I could find and could not find the "auto-adjust volume"
I had it selected ( checked) before but can no longer find it.
thanks in advance
