Aw man, I'm quite often found wanting audio compression - narrowing of the difference in loudness of sound output - but neither Win10 nor Kubuntu seem to be able to do this ootb.
It would be really good to have on a TV too (no more super-loud explosions interspersed with barely audible speech), and I'm amazed that YouTube seemingly doesn't normalise sound levels at all.
As a relatively new Win10 user I find access to mic levels being buried in device manager to be crazy. Also, not having a default output mix, apparently ...
At least games seem to offer a good range of sound settings.
