My knowledge is from being a windows user. In windows when running audio type digital modes there are 3 points of adjustment. The sound card gain, the software gain and the line in gaim. On some external sound cards there is also a pot to adjust one the sound card, that makes 4points. And there seems to be a sweet spot where they all work together and the power pops right up there and other settings where it comes up gradually, for me that seems to disappear after a transmission or two. And it might take an adjustment of one or more olf the settings to correct. Especially after a windows update. When I installed the USB board I thought maybe that would clear up, and maybe it did a bit, but I still have to tweak the settings now and then.
