By the way, what made you notice this problem in the first place? It
sounds strange that base_volume would somehow be a better volume for a
sink than PA_VOLUME_NORM when using passthrough. That's because if
base_volume does not equal PA_VOLUME_NORM, that means that hardware
volume with dB information is being used. I'd be surprised if on some
hardware there was an alsa volume element that would actually do
something useful in the passthrough mode.
