Audio benchmark and state of support

[Pander]

I am wondering if audio benchmarking is relevant for all hardware in this test setup.

Also, could there be some articles on the support currently out there by Debian an Ubuntu. For starters, I have a list of software upgrades that these distributors could pick up on (alsa, gstreamer, pukseaudio, etc.) and what is the benefit in terms of performance and support of formats, options and hardware.
