I've seen several threads related to stream volume, but most of them are with respect to a single audio device and don't seem to directly answer my question. In my case, overall audio in the output stream (regardless of source) seems to be too low for some of my viewers. iPads seem to suffer the most. They don't tend to have very loud sound. Even with volume sliders turned all the way up, compression on and desktop audio at 100%, I still get some complaints. I've worked around the problem by adding between 4 and 8dB to all input sources in the Advance Audio Settings, but if I touch the volume sliders, they get removed. I've also had some success with adding gain filters to all inputs, but this seems wrong; when the signal is constantly in the yellow or red, I should not need to add gain. Is there a master control that I've missed to increase the overall audio volume in the stream?
