Is it possible that no one has encountered this bug? Or have people
found a way around it? I've tried many workarounds and researched as
much as I can. Any ideas of how to work around this would be very
appreciated. I tried "-klg:" and "-kl2:" with an "end-value" of zero,
but they only work once through. Once you rewind, "-ea:" is stuck at
zero volume. Doing a "cs-remove/cs-add" is not feasible with what I'm
trying to accomplish.
