Device Volume too low

[ccsmart]

First up, my kudos for this project. An issue i have is with the ESP32-S3-BOX-3 devices speaker volume, which is way too low, as in noticeable only if the room is dead silent. Web research seems to indicate that its not specific to willow. The question how to increase speaker volume comes up eg on esphome as well. I tested with two brand new devices which i flashed with willow first thing (ie before going through preinstalled demo, whatever). The two have an ever so slight difference in volume. Im thinking the setting in WAS config server might be a relative "channel" volume to some other "total/overall" volume the latter of which would then be very low. Whatever the cause, despite research, i am unable to get the volume up such that for all practical means, there is no audio. Maybe somebody has a hint... ? Thanks.
