There will _always_ be new hardware, and users will _always_ have to tweak things manually.

That sounds like a recipe for disaster to me. I've often had to play around with levels for PCM vs. Master vs. other things to maximise the resulting volume¹ without introducing distortion -- you're effectively downgrading my audio capabilities unless you _always_ get it absolutely right. On which topic, see above. And then factor in the observation that we're talking about analogue circuitry and physical devices which will even vary a little from one machine to the next machine off the production line. Not to mention what my ears can detect. Your database _cannot_ know. -- David Woodhouse Open Source Technology Centre David.Woodhouse@xxxxxxxxx Intel Corporation ¹ And that's even without the bit where I plug in external speakers and want to use those in _addition_ to the internal ones, which PA also breaks. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
