FWIW: With my BCD996P2, I *do* observe this behavior with 1.10.01 firmware. (I have not updated the firmware)With my BCD996P2 I have NOT observed this behavior.
With mute enabled or the volume turned all the way to zero, I hear no audio, regardless of channel volume offset settings.
Using v22.1 as of today. Never experienced that with previous versions.

WIth the volume turned to 0, I hear audio through the speaker on a p25 talkgroup with volume offset = +3.
This appears to be an issue with the Uniden firmware - not ProScan. I would expect that the volume offset be ignored when the volume is set to 0 so that the speaker is muted.
