Why is the course audio so low? Is there something I can do on my end to correct it?
There is a volume bar on the lower right, which looks to be set to 50% by default. The course, at 50%, sounds about equivalent to YouTube at 10-20%, so you’re not just imagining that its on the quiet side.
Even at 100% I have to crank the receiver up to 40 or so before I can hear anything. This should really be looked at.
